Question

The metabolic activities of root cells are the main cause of water absorption in

• A. Passive absorption
• B. Active absorption
• C. Both passive and active absorption
• D. None of the above

Answer 1

Answer: (B)

Active absorption

The metabolic activities of root cells are the main cause of water absorption in the active absorption because the increased metabolic activity uses the energy and push the water from the region of lower concentration to the region of higher concentration against the concentration gradient.

So, the correct answer is option B.
