Question

Explain about the factors that affect water absorption.

Answer 1

1. Water is absorbed from the soil by unicellular root hairs.
2. The presence of capillary water in the soil is required because this water is absorbed by root hairs.
3. Water absorption is enhanced by soil temperatures ranging from 20 to 30 degrees Celsius.
4. High solute concentrations in soil reduce the absorption rate.
5. Soil should be properly aerated; poorly aerated soil absorbs poorly.
6. Increased transpiration enhances the rate of water absorption.
