The gymnosperms are a group of seed-producing plants. "Gymnosperm" means naked seed. Gymnosperms were the dominant land plants in the age of dinosaurs.

A roly poly is an animal that has a segmented body. The "pill bug" is a small, segmented land creature that can roll into a tiny ball for protection. The pill bug is not an insect, it is an isopod. |
Cohesion is the property of like molecules to stick to each other due to mutual attraction. Adhesion is the property of different molecules or surfaces to cling to each other.
Mycorrhizae, also known as fungus, is between the roots of a vascular plant. Mycorrhizae is usually the color green. On my tree it looks exactly like the leafs that belong to the tree, but if you looked closely at my tree you would be able to tell the difference between the actual leaves and the fungus. When you see the mycorrhizae you are actually supposed to pull them off of the tree, because this is not healthy for the tree. It will eventually take over.
Radial symmetry in animals is a line going down the front of their body. I used a ruler to show the radial symmetry of my dog. This symmetry starts from the front of the animals head and goes straight down. 
These roots have grown over time into the ground. This is known as succession. Succession is a gradual process by which ecosystems change and develop over time (dictionary.com). There are two types of succession, primary and secondary succession. This picture is a secondary succession because this happened after a tree was cut down in my community.

The cuticle layer of a plant covers the epidermis of the green part of the plant. The cuticle layer protects the plant against "UV radiation and physical and chemical biological agents" (www.uni-muenster.de).
Dogs are endothermic animals or "warm blooded" mammals. Their body heat is controlled by their metabolic rate just like humans and other mammals. Dogs start panting when they are hot so their body can cool down (earthlife.net)
Cambium is on the inside of the stem of the tree. Cambium produces new phloem on the outside of the tree and new xylem on the inside of the stems and roots of the tree. This forms the rings of the tree.
Commensalism is where two organisms benefit from each other. So if there is a squirrel, the squirrel will benefit from this tree because it would be as a home for the squirrel. The tree would also benefit from the squirrel because sometimes squirrels forget their nuts inside the tree and if the nuts fall out of the tree, a new tree would end up growing because of the seeds of the nuts. So both organisms benefit from each other.
Bilateral symmetry is something that is divisible into symmetrical halves. Bilateral symmetry, as shown with the ruler along my dog is cut along a central axis, so that the body is divided into equivalent right and left halves.
These two pictures are homologous structures. There is a difference between a dog arm and a human arm. They have different structures and different jobs.
Analogous structures look similar, or perform similar functions, but they did not come from the same ancestral source.

Basidiomycete is a type of fungus which produces "their basidia and basidiospores on or in a basidiocarp" (www.botany.hawaii.edu). Basidium is variable. 

A unicellular organism is also known as a single celled organism. This potato would be considered a unicellular organism. however, a potato plant would be considered as a multicellular organism because it has more than one potato.
A rhizome is the modified root or stem of a plant. It is usually found underground so you would have to pull it out to see it. Some plants have the rhizome sticking out of the ground. Rhizomes develop from axillary buds. The rhizome is also used as a storage for starches. Sometimes if the rhizome is separated into pieces it will allow new plants to grow.


The stigma is the tip of the carpel of a flower. The stigma will get pollen and adapts to catch and trap pollen.
