Question

Statement A: Most minerals enter the epidermal cells passively. Statement B: Uptake of water is by the process of diffusion.

• A. Both the statements are true
• B. Both the statements are false
• C. Statement A is true but Statement B is false
• D. Statement B is true but Statement A is false

Answer 1

Answer:

B. Both the statements are false

• Most of the minerals enter the cytoplasm of epidermal cells actively.

• Few of the minerals in form of ions are transported passively through the epidermal cells.

• The active uptake of ions and minerals is responsible for establishment of water potential gradient in roots, and therefore for the uptake of water by osmosis.
