AP Biology

Cells transport substances across their membrane. Choose THREE of the following four types of cellular
Osmosis Active transport Facilitated diffusion Endo/exocytosis
For each of the three transport types you choose,
a. Describe the transport process and explain how the organization of cell membranes functions in the movement of specific molecules across the membrane; and
b. explain the significance of each type of transport to a specific cell ( you may use different cell types as examples)

This is one of my AP practice homeworks, and i don't know how to do this one.Please help.
