Question

The form of water absorbed by plant's root system, from the soil is

• A. Hygroscopic water
• B. Gravitational water
• C. Capillary water
• D. All of the above

Answer 1

The correct option is C Capillary water

Capillary water is the water present in capillary spaces between soil particles. This water is available to plants for absorption and as this water is absorbed the free space generated is occupied by air. The gravitational water is the water, that has run to the water table under the influence of gravity and is not available to plants.

The hygroscopic water is present in a thin hygroscopic layer around soil particles. This water is held so tightly around the soil particle, that it is not available to plants for absorption.
