Answer: Diffusion and osmosis
Explanation:
Water, like many molecules, wants to be at equilibrium; it wants to have an equal concentration on either side of the membrane. The movement of water across a membrane to reach equilibrium is called osmosis. Water molecules move through the phospholipid molecules in the cell membrane by osmosis.
Osmosis is a process through which the molecules pass through a semipermeable membrane across a concentration gradient. Water molecules pass from high concentration to low concentration.
