Question

Plants absorb ______ water.

Options

• gravitational

• capillary

• combined

• hygroscopic

Answer 1

Plants absorb capillary water.

Explanation:

Plants absorb capillary water, which is the water held in soil pores and available for root uptake. Gravitational water drains away, and hygroscopic and combined water are bound to soil particles, so plants cannot absorb them. Hence, capillary water is the main source of water for plants.
