Question

Which of the following are/are the functions of root hair?

• A. Increase the surface area of the root for absorption of water
• B. They help in the transport of food
• C. They carry out photosynthesis under the soil.
• D. They store the extra food that is produced by the leaves.

Answer 1

The correct option is A Increase the surface area of the root for absorption of water

Plants grow root hairs on the tips of their roots. This helps to increase the surface area of absorption of water and nutrients from the soil.

Phloem help in the transport of food.

Many plants store food in the form of starch in their leaves or in modified roots such as potatoes.

In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts.
