During osmosis, flow of water through a semipermeable membrane is:

During osmosis, flow of water through a semipermeable membrane is:
  1. from solution having lower concentration only
  2. from solution having higher concentration only
  3. from both sides of semipermeable membrane with equal flow rates
  4. from both sides of semipermeable membrane with unequal flow rates

Solution

Osmosis is the phenomenon of flow of pure solvent from the solvent to the solution or from a less concentrated solution to a more concentrated solution through a semipermeable membrane. Common semipermeable membranes are permeable to certain solute particles also. Infact, there is no perfect semipermeable membrane. Therefore, we can say that flow of water through a semipermeable membrane takes place both sides with unequal rates.
