Cell Biology Slides - 8/10/99 - 1 of 3

	1) Topology of a plasma membrane when pulled into an aqueous region
	2)Villi of the small intestine - Epithelia (Outer layer) vs. Mesenchym(inner cells)
	3) Different cells demonstrating all cell have a plasma membrane
	4) Stained cells viewed under light Microscope (Do you see PM? NO)
	5) EM of plasma membrane - Glycocalyx - sugar coat surrounding cell
	6) Polar head groups give the membrane a charge potential
	7) Cholesterol used to fill the leaks of the PM
	8) Peripheral protein network of cells
	9) Plasma membrane EM-sugar moieties not internal to the membrane
