Question

The root hairs absorb which of the following type of water?

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

Answer 1

The correct option is A Capillary water

The water that is found in the capillary spaces, called capillary water, it is this water that is available to the roots. So the capillary water is the main source of useful water in the soil for the plants. Moreover, capillary system provides a network of spaces for aeration as well as movement of water from one region to another region within the soil. As roots with their numerous branches and millions of root hairs deplete water from capillary spaces, water from the other regions move into the depleted spaces; sometimes the water moves upwards from the water table and fills up the capillary spaces.
