Question

Which one is best to reduce the rate of water absorption and also acts as respiratory inhibitor?

• A. IAA
• B. KCM
• C. Transpiration
• D. Osmotic pressure of cell sap

Answer 1

The correct option is A IAA

IAA (indole acetic acid) is a respiratory inhibitor. Its application also reduces the rate of water absorption. Potassium cyanide is also a respiratory inhibitor. Transpiration facilitates the rate of absorption. The rate of water absorption increases with the gradual increase in osmotic pressure of cell sap of root hairs.

Thus, the correct answer is option A.
