Here's why:

* Location: Root hair cells are specialized cells located at the tips of roots. They extend outward from the root, increasing the surface area for absorption.

* Structure: Root hair cells have a large surface area and thin cell walls, which allows for efficient water uptake. They also have a high concentration of vacuoles, which help store the absorbed water.

* Function: Their primary function is to absorb water and dissolved minerals from the soil and transport them to the rest of the plant.
