Question

Choose the correct answers from the alternatives given.
Root hairs do not play a role in

• A. Water uptake
• B. Oxygen uptake
• C. Carbon dioxide uptake
• D. Mineral uptake

Answer 1

The correct option is C Carbon dioxide uptake

Root hairs are the tiny structures that are present on the roots. These help in the absorption of water, oxygen, and various nutrients present in the soil. Since the concentration of carbon dioxide is negligible in the soil, it is not absorbed but given out during the process of respiration by root.

Hence,the correct answer is 'Carbon dioxide uptake'.
