Question

Addition of KCN reduces the rate of water absorption in the root. This indicates the water absorption is a/an

• A. Passive process
• B. Energy dependent process
• C. Osmotic difference dependent process
• D. Exchange diffusion process

Answer 1

The correct option is A Passive process

In passive absorption, the root cells don't play an active role. In passive absorption, water moves through apoplast of leaves. It occurs due to the tension created in the xylem sap by transpiration pull.

So, the correct option is 'Passive process'.
