Explain what semi-permeable means
Web1. Description of Diffusion and Osmosis. A water solution that contains nutrients, wastes, gases, salts and other substances surrounds cells. This is the external environment of a cell. The cell’s outer surface of the plasma membrane is in contact with this external environment, while the inner surface is in contact with the cytoplasm. WebMar 24, 2024 · It is diffusion caused by osmotic pressure. The water moves from the side that has a lower solute concentration to the side that has a higher solute concentration. This is done regardless of the amount of water on either side and can result in one side of the membrane having larger volume of water.
