Questions
Explain factors affecting water absorption.
Write any four factors affecting water absorption in plants.
Solution
- The presence of capillary water is essential.
- Rate of water absorption is maximum at soil temperature between 20° to 30°C.
- High concentrations of solutes in soil water reduce the rate of absorption of water.
- Poorly aerated soil shows poor absorption rates.
- Increased transpiration accelerates the rate of absorption of water in the irrigated soil.
