Movement of water molecules along their concentration gradient through a selectively permeable membrane is known as _______.
Osmosis
Movement of water molecules along their concentration gradient through a selectively permeable membrane is known as osmosis whereas diffusion is the net passive movement of particles (atoms, ions or molecules) from a region in which they are in higher concentration to regions of lower concentration. Plasmolysis is the processes of contraction of the protoplast of a plant cell as a result of loss of water from the cell. Hydrolysis is the chemical breakdown of a compound due to reaction with water.
