User: what is a root hair cell?

Weegy: A root hair cell is a cell that's part of the smallest roots of a plants; they absorb water and nutriments from the soil. From [www.rothamsted.ac.uk/notebook/courses/guide/rthair.htm] : "Root hair cells have to be able to absorb large amounts [ of water, as the transpiration stream pulls up water to the leaves. As the process relies on diffusion, the cells must present a large surface area to the surrounding soil (the rate of diffusion is directly proportional to the surface area - Ficks Law). Thus, the cell wall facing the soil is elongated outwards."
