Which of the following water is available to plants?
Options
(a) hygroscopic water
(b) capillary water
(c) both hygroscopic water & capillary water
(d) gravitational water
Correct Answer:
capillary water
Explanation:
After gravitational water has drained down, a large amount of water is retained in minute interstitial spaces in the form of thin films surrounding the soil particles. This is called capillary water. It is held in the soil against the forces of gravity. It is the source of almost all the water that a plant absorbs from the soil.
