Answer:
Correct Answer: B
Solution:
Root hairs are not involved in preventing water loss due to transpiration.
They are actually involved in the absorption of water and minerals from the soil.
The root hairs are thin, finger-like projections that increase the surface area of the root, allowing for more efficient absorption of water and nutrients.
The root hairs have a large surface area and are in constant contact with the soil water, which allows for the diffusion of water and dissolved minerals into the root.
