A high school class in Maine - will contribute images to Wikipedia article and the commons until June 6, 2016. The collective goal is to contribute excellent biology diagrams to the Commons and to corresponding Wikipedia articles. This is done as part of an Advanced Placement Biology course. The lead editor is Chris Packard. This project is inspired by the 2009 Wikipedia AP Biology Project. There are many basic and important diagrams missing from biological articles and we're doing our part to fix this.

• Students will work alone, there are 43 students so we should have 43 new images with captions and labels.
• The time frame will be three weeks.
• Students will be required to write a summary of why they select a topic; hopefully, eliminating obscure, random topic selections. They also must create labels and captions for their photos
• They may add it to encyclopedia articles.
• The best of the bunch will be submitted as Wikipedia featured pictures, see other candidates here. Featured images must be in .svg (vector) format.

Feel free to discuss this project. Please notify me of any concerns; especially if they involve the behavior of my students on Wikipedia. With a little patience, this should be an inspirational experience for all.

Goals / Motivation

• To create a situation that not only vigorously enhances our ability to make quality decisions but also to improve our traction on the roads of 'Merica
• To improve the images in Wikipedia's coverage of Biology articles.
• To encourage promising students to write, create, learn, and contribute volunteer efforts through a service learning project.
• The dreaded “Research Project” is a standard hurdle for most AP Programs. Rightfully so, being that many college courses require such publications to validate your existence. This new approach to constructing a scientific document, is far more authentic and interesting. Rather than researching for a paper that is destined for the teacher's eyes and then a one way trip to the circular bin, let us contribute to the world-wide data base for others to benefit. I hope this will be an interesting and memorable project and assessment. It's funny, I can remember a number of projects and papers I wrote during my own high school experience, but I can remember no tests whatsoever.

Contributions

As you upload your projects and add them to Wikipedia please add them to the gallery below. By adding a new line which begins with the word "File" and them follows the format of my sample image. Make sure to include your caption.

  Toxoplasmosis life cycle:
  1.Cat eats prey with toxoplasmosis becoming the primary host of Toxoplasma gondii.
  2. Toxoplasma gondii disrupts the wall of the cat’s small intestine, forming oocysts, as well as tissue cysts in the brain and muscles.
  3.When the cat excretes waste, the feces is contaminated with the oocysts.
  4. The feces contaminates the surrounding plants.
  5. Organisms eat the plants consuming the oocysts, and become infected by the parasite. When consumed by another organism, the parasite invades the new host, causing the cycle to begin again.

  The cyclic light-dependent reactions occur when only the sole photosystem being used is photosystem 1. Photosystem 1 excites electrons which then cycle from the transport protein, ferredoxin (Fd), to the cytochrome complex, b6f, to another transport protein, plastocyanin (Pc), and back to photosystem I. A proton gradient is created across the thylakoid membrane (6) as protons (3) are transported from the chloroplast stroma (4) to the thylakoid lumen (5). Through chemiosmosis, ATP (9) is produced where ATP synthase (1) binds an inorganic phosphate group (8) to an ADP molecule (7).

  Excreted from the pancreas, insulin circulates through the blood before binding to an insulin receptor on a fat or muscle cell. Once insulin binds to the receptor, phosphorylation takes place and attaches to the beta-subunit, thus initiating the transduction process. A protein binds to the phosphorylated receptor protein, becoming phosphorylated as well. Once the protein detaches from the receptor protein, the signal has successfully been transported from the receptor to the newly active protein. Through a series of kinase proteins, the proteins are constantly being phosphorylated and activated. At the end of the transduction process, the activated protein binds to the PIP2 proteins embedded in the membrane. By doing so, the initial signal has successfully transmitted the extracellular signal. As a result, another protein is activated, later activating the storage vesicles found within the cell. Upon activation, the vesicle is transported to the membrane, where its membrane becomes integrated within the cellular membrane under a process known as phagocytosis. The Glut-4 protein channels that were once embedded in the storage vesicles are now embedded in the cellular membrane. Glucose can now flow into the cell through these glucose transport channels.

  Character displacement occurs when similar species that live in the same geographical region and occupy similar niches differentiate in order to minimize niche overlap and avoid competitive exclusion. Several species of Galapagos finches, shown above, display character displacement. Each closely-related species differs in beak size and beak depth, allowing them to coexist in the same region since each species eats a different type of seed: the seed best fit for its unique beak. The finches with the deeper, stronger beaks consume large, tough seeds, while the finches with smaller beaks consume the smaller, softer seeds.

  There are three different types of cartilage; hyaline (A), elastic (B), and fibrous (C). In elastic cartilage the cells are closer together creating less intercellular space. Elastic cartilage is found in the external ear flaps and in parts of the larynx. Hyaline cartilage has less cells than elastic cartilage, there is more intercellular space. Hyaline cartilage is found in the nose, ears, trachea, parts of the larynx, and smaller respiratory tubes. Fibrous cartilage has the least amount of cells so it has the most amount of intercellular space. Fibrous cartilage is found in the spine and the menisci.

  This vein (4) shows the interaction between the malaria sporozoites (6) with sickle cells (3) and regular cells (1). While malaria is still affecting the regular cells (2), the ratio of sickle to regular cells is 50/50 due to sickle cell anemia being a heterozygous trait, so the malaria can’t affect enough cells with schizonts (5) to harm the body.

  There are three basic variants of immunoglobulin antigens in humans that share a very similar chemical structure but are distinctly different. Red circles show where there are differences in chemical structure in the antigen-binding site (sometimes called the antibody-combining site) of human immunoglobulin. Notice the O-type antigen does not have a binding site.

  The dinoflagellate labeled above is the microscopic algae Karenia brevis. Karenia brevis is the cause of red tide in the Gulf of Mexico. The algae propels itself by using a longitudinal flagellum (A) and a transverse flagellum (B). The longitudinal flagellum lies in a groove- like structure called the cingulum (F). The dinoflagellate is separated into an upper portion called the epitheca (C) where the apical horn resides (E) and a lower portion called the hypotheca (D).

  Muscles will contract or relax when they receive signals from the nervous system. The neuromuscular junction is the site of the signal exchange. The steps of this process in vertebrates occur as follows:(`) The action potential reaches the axon terminal. (2) Voltage-dependent calcium gates open, allowing calcium to enter the axon terminal. (3) Neurotransmitter vesicles fuse with the presynaptic membrane and acetylcholine (ACh) is released into the synaptic cleft via exocytosis. (4) ACh binds to postsynaptic receptors on the sarcolemma. (5) This binding causes ion channels to open and allows sodium ions to flow across the membrane into the muscle cell. (6) The flow of sodium ions across the membrane into the muscle cell generates an action potential which travels to the myofibril and results in muscle contraction.

  The C4 pathway contains a special structure in the leaves known as Kranz anatomy. There exists a layer of mesophyll cells that contain small chloroplasts encircling bundle sheath cells that have large chloroplasts necessary for the Calvin cycle.
  A: Mesophyll Cell
  B: Chloroplast
  C: Vascular Tissue
  D: Bundle Sheath Cell
  E: Stroma
  F: Vascular Tissue: provides continuous source of water
  1) Carbon is fixed to produce oxaloacetate by PEP carboxylase.
  2) The four carbon molecule then exits the cell and enters the chloroplasts of bundle sheath cells.
  3) It is then broken down releasing carbon dioxide and producing pyruvate. Carbon dioxide combines with ribulose bisphosphate and proceeds to the Calvin Cycle.
  4) Pyruvate re-enters the mesophyll cell. It then reacts with ATP to produce the beginning compound of the C4 cycle.

  The BRCA genes are tumor suppressor genes pictured here on their respective chromosomes. BRCA 1 has the cytogenetic location 17q21 or the q arm of Chromosome 17 at position 21. BRCA 2 has the cytogenetic location 13q12.3 or the q arm of Chromosome 13 at position 12.3. Both genes produce proteins that help repair damaged DNA, keeping the genetic material of the cell stable. A damaged BRCA gene in either location can lead to increased risk of cancer, particularly breast or ovarian in women.

  Reindeer introduced to St. Matthew Island in 1944 increased from 29 animals at that time to 6,000 in the summer of 1963, a drastic overshoot of the island’s carrying capacity causing a crash die-off the following winter to 42 animals. Based on the size of the island, recent estimates put the carrying capacity at about 1,670 animals [Klein, D. R. (n.d.). The Introduction, Increase, and Crash of Reindeer on St. Matthew Island.

  In both stages of metamorphosis, the insect begins the cycle as an egg. In a complete metamorphosis the insect passes through four distinct phases which produce an adult that does not resemble the larvae. In an incomplete metamorphosis an insect does not go through a full transformation, but instead transitions from a nymph to an adult by molting its exoskeleton whenever it becomes too tight.https://www.cals.ncsu.edu/course/ent425/tutorial/morphogenesis.html

  Hemoglobin and Chlorophyll, two extremely different molecules when it comes to function, are amazingly similar when it comes to its atomic shape.There are only three major structural differences; a magnesium atom (Mg) in chlorophyll, which is replaced with iron (Fe) in hemoglobin. Additionally, chlorophyll has some extra structures on the bottom right side (A), and an extended hydrocarbon tail on the left (B). These differences cause the chlorophyll molecule to be non-polar, in contrast to the polar hemoglobin molecule.

  Mammals and insects are part of different homologous and analogous evolutionary groups. In the horizontal direction, the structures are homologous in their morphology, or anatomy, but different in their function due to differences in habitat. In the vertical direction, the structures are analogous in function due to similar lifestyles of organisms but anatomically different since they are part of different groups.

  Sexual selection is a form of natural selection where one sex prefers a specific characteristic in an individual of the other sex. Peafowls exhibit sexual selection in that peahens look for peacocks who have more “eyes” on their tail feathers. If a peacock has fewer “eyes”, then the peahen will continue to look for a better, more suitable mate. This will eventually cause the peacocks with fewer eyes to die out and the peacocks with more “eyes” to continue to grow in proportion to the population size.

  Often used as a cancer treatment in postmenopausal women, aromatase inhibitors work by blocking the conversion of androstenedione and testosterone into estrone and estradiol, respectively, which are both crucial to the growth of developing breast cancers (aromatase inhibitors are also effective at treating ovarian cancer, but less commonly so). In the diagram, the adrenal gland (1) releases androstenedione (3) while the ovaries (2) secrete testosterone (4). Both hormones travel to peripheral tissues or a breast cell (5), where they would be converted into estrone (8) or estradiol (9) if not for aromatase inhibitors (7), which prevent the enzyme CYP19AI (also known as aromatase or estrogen synthase) (6) from catalyzing the reaction that turns androstenedione and testosterone into estrone and estradiol. In the diagram, Part A represents the successful conversion of androstenedione and testosterone into estrone and estradiol in the liver. Part B represents the blockage of this conversion by aromatase inhibitors both in peripheral tissues and in the breast tumor itself.

  Blood glucose levels are maintained at a constant level in the body by a negative feedback mechanism. When the blood glucose level is too high, the pancreas secretes insulin and when the level is too low, the pancreas then secretes glucagon. The flat line shown represents the homeostatic set point. The sinusoidal line represents the blood glucose level.

  Lamarckian inheritance is the idea that individuals can pass down traits acquired during their lifetime to their offspring. This diagram is an example that supports Lamarckian inheritance. The first giraffe has a short neck and cannot reach the leaves to eat. Over time the first giraffe would create a gene that would say it needed a longer neck to reach the food and it would then pass down the trait to its offspring to have a longer neck, so it could reach the food. By the fourth giraffe, it would be able to reach the leaves due to its extended neck length, which has changed over multiple generations.

  Ribonucleoproteins (snRNPs) are subunits of spliceosomes (small RNA and proteins). SnRNPs cut the DNA and remove noncoding introns (2) from the coding exons (1). This is an accessible process to producing a mature mRNA for RNA translation. The introns are cut at the 5’ and 3’ splice sites.The U1 snRNP binds to the 5’ splice site, while U6 snRNP binds to the 3’ splice site. Then U2, U4, U5 binds in the intron region (branch site). The 5’ splice site on the end of the intron is cut first. The free 5’ end then bonded to an adenine in the branch site.U1 and U4 snRNPs are released as the U3, U5, U6 snRNPs shift on the lariat (the removed intron with the snRNPs attached). The 3’ splice site is cut and the exon sites are connected. The lariat then disintegrates away from the exons.Mature mRNA is left.

  1. Excess nutrients are applied to the soil. 2. Some nutrients leach into the soil where they can remain for years. Eventually, they get drained into the water body. 3. Some nutrients run off over the ground into the body of water. 4. The excess nutrients cause an algal bloom. 5. The algal bloom blocks the light of the sun from reaching the bottom of the water body. 6. The plants beneath the algal bloom die because they cannot get sunlight to photosynthesize. 7. Eventually, the algal bloom dies and sinks to the bottom of the lake. Bacteria begins to decompose the remains, using up oxygen for respiration. 8. The decomposition causes the water to become depleted of oxygen. Larger life forms, such as fish, suffocate to death. This body of water can no longer support life.

  Phagocytosis is the process in which a cell engulfs a particle, digests it, and expels the waste products. Process of phagocytosis: 1. A particle is ingested by a phagocyte after antigens are recognized which results in the formation of a phagosome. 2. The fusion of lysosomes with the phagosome creates a phagolysosome. 3. The particle is broken down by the digestive enzymes found in the lysosomes. The resulting waste material is discharged from the phagocyte by exocytosis.

  Pre-mRNA is the first form of RNA created through transcription in protein synthesis. The pre-mRNA lacks structures that the messenger RNA (mRNA) requires. First all introns have to be removed from the transcribed RNA through a process known as splicing. Before the RNA is ready for export, a Poly(A)tail is added to the 3’ end of the RNA and a 5’ cap is added to the 5’ end.

  Environmental DNA (eDNA) is DNA that an organism leaves behind as it moves through an environment. Generally, eDNA follows a pattern of exponential decay over time. The fish above leaves its eDNA behind as it moves through the aquatic environment. The eDNA stays behind in the environment, and slowly dissipates over time. Barnes, M. A., Turner, C. R., Jerde, C.

  In a reflex arc, an action potential never travels to the brain for processing and so results in a much quicker reaction. When a stimulus (A) is encountered, the signal from that stimulus will travel up the sensory neuron (B, in green) to the spinal column (C). There, it will likely pass through a short interneuron (D, in purple) before continuing down a motor neuron (E, in blue) to the origin of the signal. Then, a contraction of the muscles (F) is triggered, moving the bone (G).

Uploading

In order to complete the assignment and reap all the benefits of your hard work (such as a good grade) you MUST complete all of the following steps. If you need help, just ask.

How to, step by step

Step 1: Create a Wikipedia Global account by clicking "Login/create account" in the upper right hand corner of this page.
Step 2: Click here to use the WikiCommons File Upload Wizard
Step 3: If you didn't do it in the Wizard, categorize your image by adding a one or more [[Category:_______]] tags at the bottom of the page (fill in the name of the category in the _______.) You might use Category:Biology diagrams (but that's not a very helpful category) or something more specific like Category:Molecular biology or something else appropriate.
Step 4: If you didn't do it in the Wizard you should also now add your labels and your caption information in the description to your upload page in the Commons.
Step 5: Your image is now available in all Wiki Projects, including Wikipedia. So let's add it to the article! Go to the article you want to add your donated image to. In the top of the section of the article or the subheading you want to add the image to add something like this:

[[File:MY IMAGE NAME.png|right|thumb|200px|The [[caption]] of '''my image'''.]]
That's not too hard is it? For your caption you'll need to follow Wikipedia style and use some mark up to do this - it's kind of like a micro-essay. The [[ ]] creates a link to the given page on Wikipedia and the ''' ''' make the word bold, in Wikipedia it's appropriate to bold the title of the article the first time it's used in the text or in a caption."

Step 6: Wow you've done it! Now you just have to turn in your work by adding it to gallery in the section above here called "Contributions". Just follow the model I provided in the first entry. Make sure that your entry is between the <gallery> and </gallery> tags or it won't show up. Your caption will likely have to be shorter than your description, see the style advice below.

Style guides

To get past the stumbling blocks of editing Wikipedia, articles will have to conform to the Wikipedia style guides. The largest barriers are:

• Wikipedia:Manual of Style/Images - The basic overview of images (the Wikipedia:Picture tutorial is also useful.

Writing a good image caption

There are several criteria for a good caption. A good caption:

1. clearly identifies the subject of the picture, without detailing the obvious.
2. is succinct (that means short).
3. establishes the picture's relevance to the article.
4. provides context for the picture.
5. draws the reader into the article.

Different people read articles different ways. Some people start at the top and read each word until the end. Others read the first paragraph and scan through for other interesting information, looking especially at pictures and captions. For those readers, even if the information is adjacent in the text, they will not find it unless it is in the caption—but do not tell the whole story in the caption—use the caption to make the reader curious about the subject.

Another way of approaching the job: imagine you're giving a lecture based on the encyclopedia article, and you are using the image to illustrate the lecture. What would you say while attention is on the image? What do you want your audience to notice in the image, and why? Corollary: if you have got nothing to say, then the image probably does not belong in the article.

Images for the lead

It is very common to use an appropriate representative image for the lead of an article, often as part of an infobox. The image helps to provide a visual association for the topic, and allows readers to quickly assess if they have arrived at the right page. For most topics, the selection of a lead image is plainly obvious: a photograph or artistic work of a person, photographs of a city, or a cover of a book or album, to name a few.

Image selection for other topics may be more difficult and several possible choices could be made. While Wikipedia is not censored, as outlined in the above section on offensive images, the selection of the lead image should be made with some care with respect to this advice. Lead images are loaded and shown upon navigating to the page, and are one of the first things that readers will see. Editors should avoid using images that readers would not have expected to see when navigating to the page. Unlike other content on a page that falls below the lead, the lead image should be chosen with these considerations in mind.

Some advice on selecting a lead image include the following:

1. Lead images should be images that are natural and appropriate visual representations of the topic; they not only should be illustrating the topic specifically, but should also be the type of image that is used for similar purposes in high-quality reference works, and therefore what our readers will expect to see. Lead images are not required, and not having a lead image may be the best solution if there is no easy representation of the topic.
2. Lead images should be selected to be of least shock value; if an alternative image exists that still is an accurate representation of the topic but without shock value, it should always be preferred. For example, using an image of deportees being subjected to selection as the lead image at this version of Holocaust is far preferable to the appropriate images that appear later in the article that show the treatment of the prisoners or corpses from the camps.
3. Sometimes it is impossible to avoid the use of a lead image with perceived shock value if the topic itself is of that nature, for example in articles on various parts of human genitalia. It should be anticipated, through Wikipedia:Content disclaimer, that readers will be aware they will be exposed to potentially shocking images when navigating to articles on such topics.
