Explain about the factors that affect water absorption.

1.	Explain about the factors that affect water absorption.
Answer» 1. Water is absorbed by unicellular root hairs from soil. 2. Presence of capillary water in soil is needed as this water from soil is absorbed by root hairs. 3. Soil temperature of 20-30°C favours water absorption. 4. Rate of absorption is decreased by high concentration of solutes in soil. 5. Soil should be properly aerated, poorly aerated soil shows poor absorption rate. 6. Increased transpiration accelerates rate of absorption of water.
