diffusion osmosis bulk flow turgor pressure Question 6 1 pts Plasma membranes in both plants and animals are lipd bilayer structures which conform to the fluid mosaic model of integrated proteins Are there any significant differences between plant and animal plasma membranes No Yes they contain different types of proteins exclusive to their phyla i e there are plant proteins and animal proteins plants don t have proteins found in animals and vice verse Yes the plasma membranes of plants are composed of phospholipid and sterol compounds such as stigmasterol animals are composed of phospholipid and cholesterol The sterol compounds regulate the fluidity of the membrane more makes the membrane more rigid
