Partially permeable membrane examples
WebAll cells are surrounded by a cell membrane which is partially permeable Water can move in and out of cells by osmosis Osmosis is the diffusion of water molecules from a dilute solution to a more concentrated solution across a partially permeable membrane In doing this, water is moving down its concentration gradient WebAnswer (1 of 2): A water purifier that relys on reverse osmosis - the RO membrane is permeable to water, but rejects (most) organic molecules and salts. Like most membranes, it’s not perfect - so it will, for example, pass some simple alcohols and also ammonia and it still passes a small amount ...
