Can someone help me to describe the basic structure and functions of glycogen and the relationship of structure to function of these substances in animal cells and plant cells. (Also is glycogen soluble?)

Glycogen is a storage molecule for glucose found in animals. It has a similar purpose to starch which stores glucose in plants. It is made from alpha glucose molecules joined by glycosydic bonds. It is insoluble (so is starch) which makes it a good storage molecule as it does not affect water potential in cells. It is often highly branched which creates a large surface area for enzymes to hydrolse to release glucose when it is needed for respiration. Although it is important to note you can get both amylose and amylopectin types of glucose. Amylose is highly coiled like starch to make it more compact so more can be stored in the same amount of space while amylopectin is more branched so glucose can be accessed quicker.

Hope thats helpful!
