AP Biology

#1. Adaptation of an animal: This is my pet rabbit, Toni. At first glance he seems like a normal rabbit, but I actually saved him from impending doom when my neighbor ran over his nest when he was about twelve days old. It took him awhile to get used to his new home and family, but now a lot of things have changed ever since I kept him. One thing he has adapted in his new environment is that cottontail rabbits are usually nocturnal, but every morning when I wake up he comes over to greet me. :3 He makes me a happy owner.

#2. Thorn of a plant: This lime plant is a perfect example of a thorny plant. Thorns are used to protect the plant from some potential predators such as deer.

#3. Adaptation of a plant: Notice how this tomato plant is physically wrapping itself around the plastic tube. This is because my mother wanted it to stay strong against the wind and rain. She turns it in certain directions so that the plant adapts to the sudden directional change and grows toward the light source; wrapping itself around the tube. I think it's ingenious if you ask me.

#4. Eukaryote: This is my nephew, Dylan. Due to the fact that he is multicellular and those cells have complex organelles, he's a eukaryote.

#5. Autotroph: This basket of flowers is an example of an autotroph because it's able to produce it's own food. Some heterotrophic birds decided to nest here. D:

#6. Fruit - dry with seed: These green beans are dry fruit because it's neither fleshy nor are the seeds enclosed, they're just sitting inside.

#7. Fruit - fleshy with seed: On the other hand, all of the fruits here are fleshy fruits.

#8. Water properties - cohesion, adhesion, surface tension: The polarity of the water on this plant creates cohesion and adhesion. The cohesion and adhesion creates surface tension on the leaves of the plant.

#9. Exoskeleton: This brown butterfly has an exoskeleton, which is an external and tough covering made of chitin. This protects it's organs and supports it's body.

#10. Lichen: This gray, green stuff growing on
this tree trunk is a type of fungus called lichen. Lichen typically grow on rocks and tree trunks.

#11. Stem - Woody: The tree shown here has a woody stem because the wood is used as the structural tissue.

#12. Cuticle Layer of a plant: The leaves of a plant have a very thin film covering the surface of the plant, derived from the epidermal cells. This is the cuticle layer.

#13. Stem - Herbaceous: The aloe leaf shown here is actually a stem modified to have the same properties as a leaf, thus making it herbaceous. The real leaves are the spines sticking out of the stem itself.

#14. Insect: This red-eyed (and very hard to see) fly is an example of an insect. It has six legs and a segmented body.

#15. Frond: Ferns, like this one, are made up of fronds which are large and divided leaves.

#16. Cellulose: Cellulose is a carbohydrate and is the chief constituent in not only the cell walls of plants, but also in wood, cotton, and even plain old paper.

#17. Dicot plant with flower and leaf: Roses are examples of dicots because they have four to five petals and the seeds of roses can easily be split into two as opposed to staying as one seed.

#18. Deciduous leaf: This maple tree has deciduous leaves because the leaves fall off and grow back seasonally.

#19. Monocot plant with flower and leaf: Lillies are a type of monocots because they have one seed leaf and it's petals are in parts of threes.

#20. Fungus: These Shitake mushrooms are one of many species within the Fungae kingdom. Fungus may have cell walls, but their walls are made of chitin instead of cellulose like plants, and they do not go through photosynthesis.

#21. Endotherm: All mammals, including this cat, are endotherms. Endotherms are able to regulate their own body temperature and are usually able to keep it at a constant level.

#22. Anther and Filament of Stamen: The stamen is the male reproductive organ of a flower. The stamen has stalks called filaments, and at the top of the filament is the anther. The anther is where the pollen comes out.

#23. Amniotic Egg: The pictured snake necked turtle egg is an example of an amniotic egg. Amniotic eggs are terrestially adapt.

#24. Animal that has a segmented body: These delicious blue crabs have body plans that have repetitive segments.

#25. Arthropod: Crayfish have an exoskeleton, a segmented body, and jointed appendages. This makes them an arthropod.

#26. Chitin: Chitin is a polymer derived from glucose. It can be found in the cell walls of fungi, and in the exoskeleton of many creatures including these horseshoe shrimp.
