1. Endotherm - My cat, Zoey, is an example of an endotherm. The prefix endo- means "inside", while the suffix -therm means "heat". This simply means that she is a warm-blooded organism that regulates her own body temperature.

2. Chitin - This butterfly's exoskeleton is made of chitin, a polysaccharide found in the cell walls of arthropods. It's purpose is to help protect the organisms, like armor.

3. Stem, woody - This is a picture of a tree's stem. The outside of the stem is covered in bark, and the inside is also wooded, unlike stems of flowers.

4. Fruit, fleshy with seed - This is a picture of a wild strawberrry in my yard. Fruits are constituted as anything bearing seeds, and this strawberry bears seeds on the surface. This is also a fleshy fruit, as the inside and outside are moist and chewy. (:

5. Exoskeleton - These two beetles are examples of organisms that have exoskeletons (otherwise known as a hard shell). The prefix exo- refers to "outside", meaning that these organisms wear their skeletons on the outside of their bodies in order to protect their organs.

6. Pollinator - It's kind of difficult to see, but on the blooms of this mint bush are several tiny bees. These bees are considered pollinators because as they extract nectar for a meal, the unknowingly carry pollen from inside male parts of the blooms and take it to the female parts of another bloom, resulting in cross pollination. This helps pollinate all the surrounding plants, thus making bees crucial to help the enviroment thrive.

7. Ectotherm - The spider in this picture is an ectotherm. The prefix ecto- means "outside" or "without", and the suffix -therm means "heat", thus consistuting a spider as an ectotherm, or in other words it regulates it's body temperature externally.

8. Adaptation of an animal - Inside of this gas tank is a little birdy and it's nest (even though you can't see it). It has adapted to conditions which are not possible in the natural world, aka living in a gas tank, in order to create a shelter for itself and the offspring.

9. Deciduous leaf - These leaves are examples of deciduous leaves, since they've come from a tree. The reason they are deciduous is because they came from a deciduous tree, a tree that sheds the leaves when the season changes in order to mature.

10. Fungus - All mushrooms are fungi including this one, because they are a part of the fungi kingdom (neither plant nor animal) and have very distinct differences from animals and plants (cell walls made with chitin, fruiting bodies, etc...).

11. Commensalism - The butterflies and mint blooms are an example of the relationship commensalism, where both species interact and one benefits while the other is not affected. In this case, the butterflies benefit by getting a meal, while the mint bush is unaffected.

12. Insect - This black ant is considered an insect, as it meets the requirements to be classified as an insect: exoskeleton, three part body, two antennae, etc.

13. Pollen - In this picture, these mint blooms contain pollen, a fine to course yellow powder that hold the seeds of male gametes.

14. Arthropod - This spider is considered to eb an arthropod; arthropods consist of an exoskeleton, segmented body, and jointed appendages.

15. Radial Symmetry - This wooden star has radial symmetry. This means that the star is arranged equally in every direction around a center point, and if folded in half, the images would mirror each other.

16. Long Day Plant - A long day plant is a plant the blooms in the spring - early summer, when day light is long than night. These tulips are considered a long day plant since they bloom in early spring and last until late spring, then bloom next spring.

17. Genetically Modified Organism - These bananas are considered to be genetically modified because they have aquired one or more genes through artifical means. Generally in the US, genes are injected into these fruits in order for them to grow in off seasons, last longer, or be protected from insects.

18. Pine Cone, female - Compared to male cones, female cones are usually a lot bigger then the male cones in order to store and release the seeds. In this picture, this cone is considered a female because the spaces indicate that there were once seeds inside.

19. Fronds - Fronds are essentially large extentions of leaves. In this plant, the stems extend into large leaves with divisions of individual leaves.

20. Flower Ovary - The ovary of a flower is the reproductive part that produces seeds after being fertilized by pollen. Here in this picture, Becca is pointing towards the flower ovary, which is usually enclosed and at the bottom of the bud.

21. Modified Stem Of A Plant - The vine-like extention on this plant is an exmple of a modified stem. Stems as such are usually modified for special functions such as providing extra support for the plant.

22. Lichen - The green on this tree is lichen, a composite organism, composed of a symbiotic relationship between fungus and algae.

23. Connective Tissue - The tissue that binds together all bones, joints, etc. My hand is made up of connective tissue so it can be in tact and functional.

24. Cellulose - Cellulose is an organic compound that is the primary component of cell walls for green plants; this compound is found everywhere in the hydrengea bush.

25. Niche - The niche of an organism includes all the biotic and abiotic elements that make up its living space. This tree is a niche to many different organisms by providing food, shelter, and much more.

26. Thorn Of A Plant - The pointed extensions of this plant's stem are examples of thorns, which are one of this plant's natural defense mechanisms.

27. Autotroph - The plant is an autotroph because it produces it's own food through a process called photosynthesis.

28. Cuticle Layer Of A Plant - The cuticle layer is the outside protective layer covering over the aerial parts of land plants.

29. Animal With Segmented Body - This insect has a segmented body consisting of a head, thorax, and abdomen.

30. Water Properties: Cohesion, Adhesion, Surface Tension - Here on the grass, the H20 properties are displayed as the water droplets stick to the grass.
