Cells absorb water through

Cells absorb water through Osmosis and Imbibition only.
Both phenomena help in the metabolic activity of the plant. The process of adsorption of water by solid particles of a substance without forming a solution is called imbibition.
Osmosis is the diffusion of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Water moves into and out of cells by osmosis.
