Question

Which one of the following is correct regarding the factors that affects water absorption in plants?

• (A) Presence of capillary water is essential.
• (B) Rate of water absorption is maximum at soil temp between 20-30 degree celcius.
• (C) Both (A) and (B)
• (D) Deccreased transpiration accelerates the rate of absorption.

Answer 1

The Correct Option is C

Explanation:
Water absorption in plants occurs through the root hairs that carry the water present in the soil and forms a zone called the root hair zone. The factors that affects water absorption in plants are:Presence of capillary water is essential.Rate of water absorption is maximum at soil temp between 20-30 degree celcius.High concentration of solutes in soil water reduced the rate of absorption of water.Poorly aerated soil shows poor absorption rate.Increased transpiration accelerates the rate of absorption of water in the errigated soil. Hence the correct option is (C).
