Question

The water readily available to plants for absorption by roots is

• A. Gravitational water
• B. Capillary water
• C. Rain water
• D. Hygroscopic water

Hint:

Capillary water is the main source of water for plant absorption from soil.

Answer 1

The Correct Option is B

Step 1: Soil water exists in different forms such as gravitational, capillary, and hygroscopic water.
Step 2: Capillary water is held in the small pores of soil particles and is easily available for absorption by plant roots.
Step 3: Gravitational water drains away quickly and is not readily available, while hygroscopic water is tightly bound to soil particles and cannot be absorbed. Hence, the water readily available to plants is capillary water.
