(b) Both assertion and reason are true but reason is not the correct explanation of assertion. (c) Assertion is true but reason is false. (d) Both Assertion and Reason are false. Assertion : Absorption of water by plant roots is an example of osmosis. Reason : Cells tend to gain water through osmosis.

Answer 1

(c) Assertion is true but reason is false.

• Root cells tend to take up water through osmosis.
• When the quantity of water is more in the soil as compared to the quantity of water in a root cell, water is absorbed from the soil by the root cell through the process of osmosis.
• The reason is false because cells can either gain or lose water through osmosis. If water quantity is more inside a cell as compared to outer environment, then the water will move out of cell through osmosis.
