Root hair cells are specialized cells located on the surface of plant roots. They are not found in humans.

Here's what plant root hair cells do:

* Absorption of water and minerals: Root hair cells have a large surface area due to their elongated shape, which increases their ability to absorb water and dissolved minerals from the soil.

* Anchoring the plant: The root hairs help to anchor the plant in the soil.

* Nutrient uptake: They are responsible for taking up essential nutrients like nitrogen, phosphorus, and potassium, which are crucial for plant growth.
