Answer:
Osmosis is the passage of water through a semi-permeable membrane.
Explanation:
Osmosis is the movement of solvent molecules from a region of higher concentration to a region of lower concentration, through a differentially permeable membrane. The cell holds higher solute and lowers water concentration. When cells are put in such a solvent, water enters inside the cells. There are two types of osmosis. Exosmosis and endosmosis. Exosmosis is the flow of water out of a cell when it is placed in a hypertonic solution. Endosmosis is the flow of water to the cell when the cell is inside a hypotonic solution.
