Lichen

In this picture is a piece of rotting wood with lichen on it. Lichen is an organism that usually is made up of a fungus that grows symbiotically with algae or some cyanobacterium. Lichen usually takes up a crust-like or branching form on rocks or tree trunks. In the case of the lichen above, it seems to be a little more crust-like.

Exoskeleton

In this picture you can see a beetle, specifically a Horned Passalus. This beetle has a tough Exoskeleton to protect its soft insides from the rest of the world. An Exoskeleton is a tough layer on the outside of an animal, it is much like a humans skeleton except it supports the animals body from the outside instead of on the inside. Some examples of animals with Exoskeletons would be mollusks, arthropods, and crustaceans.

Population

In this picture you can see a collection of anthills. This collection of anthills is an example of population. A Population is when a group of the same species lives in a singular area at the same moment in time. A group of anthills would be an example of population because they are all of the same species and they are residing in the same area at the same time.

C4 Plant

In this picture is some grass. Grass is an example of a C4 plant since it is better at photosynthesis in hot, sunny weather. Other examples of C4 plants are crops like sugarcane and corn. C4 plants fix the carbon into C4 in their cytoplasm before they begin their calvin cycle.

Gymnosperm cone

Within this picture you can see a pine cone. A pine cone is an example of a Gymnosperm cone. A Gymnosperm is a plant that has unprotected seeds, their seeds usually form into cones. Some examples of Gymnosperms are conifers, cycads, and ginkgo.

C3 Plant

In this picture you can see some oak trees. Oak trees are an example of a C3 plant. C3 plants are the most common kind of plant, in fact they include about 95% of all the plants on earth. C3 Plants are the most efficient at photosynthesis in cooler, wetter climates. C3 plants change CO2 into a tree carbon compound before beginning the Calvin cycle for photosynthesis.

Frond

In this picture is a fern. A fern is also part of a group called the Fronds. Fronds have large compound leaves, which means that they have a bunch of tiny separated parts all connected to a rachis (the center of the leaf). Examples of Frond plants are Palm trees, ferns, and other similar plants.
