1 answer the question correctly to continue reading
what is the main function of the root hairs on a plant’s roots?
a to absorb water and nutrients
b to take in carbon dioxide
c to anchor the plant in the ground
d to produce oxygen

Explanation:

• Option A: Root hairs are extensions of root epidermal cells that increase the surface area for absorbing water and dissolved nutrients from the soil.
• Option B: Carbon dioxide intake occurs mainly through stomata in leaves, not root hairs.
• Option C: The main anchoring function is done by the root system (e.g., taproots, fibrous roots), not specifically root hairs.
• Option D: Oxygen production is from photosynthesis in leaves, not root hairs.

So the correct answer is A.

Answer:

A. To absorb water and nutrients
