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 Thus, the cell wall facing the soil is elongated outwards.

They are a useful part in the plan. They collect water from underground. Strangely though, as they are plant cells, they don't have any chloroplasts. That is because they don't need them. Obviously, being roots, they are underground so coul...
