Question

Water will be absorbed by the root hair because:

• A. Concentration of solutes in the cell sap in root hair cell is high.
• B. Plant is rapidly respiring.
• C. They are separated from soil by permeable membrane.
• D. Concentration of salts in the soil is high.

Answer 1

The correct option is A Concentration of solutes in the cell sap in root hair cell is high.

Root hairs are the outgrowths at the tip of the plant root. They are involved in water absorption and they increase the surface area for water absorption. The osmosis of water occurs in the root hair due to the presence of a high concentration of solutes in the cell sap.

So, the correct answer is option A.
