Question

Water will be absorbed by root hair by

• A. Osmosis
• B. Active Transport
• C. Transpiration
• D. Evaporation

Answer 1

The correct option is A

Osmosis

The absorption of water mainly takes place at the terminal ends of the roots but occurs maximum in the area of root hair (1-10 cm behind the root tip). A root hair contains cell sap which has a higher concentration of salts as compared to the soil water. Hence the root hair cells absorb water from the soil by endosmosis.
