The process by which molecules of a solvent tend to pass through a semipermeable membrane from less concentrated solution into a more concentrated one is called:?

Option 3 : Osmosis

Concept-

• Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecule or ions to pass through it by osmosis.
• It can’t be pass substances some molecule such as hydrocarbon and oxygen can cross the membrane.
• This membrane cell to exchange nutrients and waste with blood.

Explanation-

• Movement of solvent (water) across a semipermeable membrane from an area of high water concentration to an area of lower water concentration.
• Example of osmosis -> The absorption of water from the soil is due to osmosis. The plant roots have a higher concentration than the soil. That’s why water flows into roots.
• Types of osmotic solutions:

1. Isotonic solution
2. Hypertonic solution
3. Hypotonic solution

• Ultrafiltration- it is pressure driven barriers to suspended solids, bacteria, viruses, endotoxin and pathogen to produce water with high purity and low slit density.
• Active transport – active transport is the movement of molecules across a cell membrane from region of lower to higher concentration region.
• Diffusion- diffusion is a passive movement of molecule from a region of higher to lowe region concentration.
