What is osmosis?

Osmosis is the process by which water molecules move from a region of higher water concentration to a region of lower water concentration through a selectively permeable membrane.

This movement continues until the concentration of water becomes balanced on both sides of the membrane.

Osmosis is important in living organisms because it helps in the absorption of water by plant roots, maintenance of cell shape, and regulation of water balance in cells.

For example, plant roots absorb water from the soil through osmosis, which helps maintain turgidity and supports plant growth.

Osmosis is a passive process, meaning it does not require energy.
