The outer layer of a root that contains root hairs is called the epidermis. The root hairs are extensions of the epidermal cells that increase the surface area for water and nutrient absorption from the soil. This layer plays a crucial role in the plant's ability to take up essential resources for growth and development.

How would you recognize the epidermis of a root versus the epidermis of a leaf?

The lower epidermal layer of leaf has many holes (stomata) in it and guard cells surrounding these holes. In the roots the epidermis has many root hairs growing out of it or regions of dead root hairs where over time the roots have grown longer and the old root hairs are no longer needed to capture water. In the upper epidermis of a leaf you would see palisade cells just beneath the epidermal layer and a waxy cuticle just above.
