The movement of water molecules through selectively permeable membrane along concentration gradient is called osmosis. It is the passage of water from region of high water concentration through semi permeable membrane to a region of low water concentration (only through semi permeable membrane) Unicellular freshwater organisms and most plant ceils tend to gain water through osmosis. Absorption of water by plant roots is also an example of osmosis.

The passage of water from a region of higher water concentration throu...
Explanation:
Definition:
Osmosis is the passage of water from a region of higher water concentration through a semi-permeable membrane to a region of lower water concentration.
Process:
- Water molecules move from an area of high water concentration to an area of low water concentration through a semi-permeable membrane.
- The semi-permeable membrane allows water molecules to pass through, but restricts the movement of solute particles.
- The movement of water continues until equilibrium is reached, where the concentration of water is the same on both sides of the membrane.
Key Points:
- Osmosis is a passive process that does not require energy input.
- It plays a crucial role in biological systems, such as the movement of water in plant cells.
- Osmosis helps maintain the balance of water and solutes within cells and tissues.
In conclusion, the passage of water from a region of higher water concentration through a semi-permeable membrane to a region of lower water concentration is known as osmosis.
