The cell wall: Outer most porous layer in prokaryotic, protist, fungi, and plant cell. Not found in animal cells. It protects and provides support .
In plants it is made mostly of cellulose fibers (a carbohydrate)

Proteins embedded in the cell membrane
. Marker proteins: Different from person to person. They are like the id. of cells. Important in the function of the immune system. Why?
Channel proteins: are like tunnels that let molecules that fit go in or out of the cell. Oct 11­10:15 AM
