Membrane structure and function biology essay chapter rubric: membrane structure and function the ability of the cell to know apart in its chemical exchanges with the environment is cardinal to life, and it is the plasma membrane that makes this selectivity possible. How do membranes and cell walls that surround cells control the movement of materials in and out of living cells relate membrane and wall structure to such processes as diffusion, osmosis, pinocytosis and phagocytosis the surrounding cell walls and membranes can control the materials that pass in. Osmosis is the diffusion of water (solvent) across a selectively permeable membrane a) the osmotic pressure is the tendency of water to move into that solution b) two solutions may be isotonic to each other, or one may be relatively hypertonic and the other relatively hypotonic (1) human cells are isotonic, with a 09% sodium chloride solution.
