Question

Which of the following forms of soil-water is commonly absorbed by plants?

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

Answer 1

The correct option is B Capillary water

Capillary water is present in the capillary spaces between soil particles and this water is easily available to plant roots for absorption. Hygroscopic water is present as a thin film around soil particles and is not available to plant roots. Gravitational water is the water that seeps down to the water table under the influence of gravity. It is also not available for plants.

Thus, the correct answer is option B.
