Question

The function of a root hair is to allow water to evaporate from plant leaves in a process called transpiration. increase the surface area available for absorption in plant roots. serve as a waxy barrier that allows plants to be selective about what enters the xylem. prevent water and soil nutrients from moving through the cytoplasm of root cells into the root. prevent water and soil nutrients from moving through cell walls into the root. Which the following allows plants to be selective about the molecules that enter the xylem? A waxy barrier in the plant root. Transpiration. Pores in the leaf. The transpiration-cohesion-tension mechanism. Cohesion.

Explanation / Answer

1. Well the root hairs are are the large number of microscopic elongated outgrowth which increases the surface area for absorption of water and nutrients from the soil.

2. Well the waxy barrier on the roots of the plant make it mire selective about the molecules that enter the xylem.
