Objective: 2.03 Investigate and analyze the cell as a living system including:
 * maintenance of homeostasis
 * movement of materials into and out of the cell
 * energy use and release in biochemical reactions

Research the fluid mosaic model of the plasma membrane using the internet. Complete the following: 1. Draw and label a diagram of the cell membrane:

2. Discuss the structure of a phospholipid (include picture) and how it relates to the structure of the plasma membrane.

3. What is the function of each in the plasma membrane: a. Carbohydrate Chain

b. Protein

c. Cholesterol

4. Why is the cell membrane so important to the maintenance of homeostasis in the cell?
