The plasma membrane (cell membrane):
a) Surrounds the cell wall and serves to protect the cell from changes in osmotic pressure
b) is a polysaccharide-containing structure that functions in attachment to solid surfaces, preventing desiccation and protection
c) Is a non-permeable membrane enclosing the cell wall
d) Is a dynamic, selectively permeable membrane enclosing the cytoplasm.
The plasma membrane Is a dynamic, selectively permeable membrane enclosing the cytoplasm. 7.5-10nm thick. Located between the cell wall and the cytoplasm. Essential for passive nutrient diffusion and active transport across the membrane (requires energy). Consists of a PHOSPHOLIPID BIOLAYER called fluid MOSIAC found in both prokaryotic and eukaryotic. Cell wall surrounds membrane to protect from changes in osmotic pressure, anchor flagella, transport molecules etc... Mitochondrion contains inner membrane and outer membrane (as does the nucleus)
