What is a root hair cell and what does it do?

A root hair cell is on the root of a plant, specially designed so it has a large surface area to abosorb water which will be taken up the stem by xylem and used in photosynthesis.

Also, it has a large permenant vacuole to speed up the movement of water by osmosis.

Hope this helped!

Because a plant cell has to absorb the water from the soil by osmosis they use a root hair cell there adaptation is a ‘long finger like’ which processes with a very thin wall, which gives a very large surface area and a thin cell membrane which helps speed up the osmosis. Due to root hair cells not being able to carry out photosynthesis they do not contain chloroplasts. When the root hair cells absorb the water it is transferred through the roots to the rest of the plant where it is used for different purposes for example it is a reactant which is used in photosynthesis also it supports the leaves by keeping the cells rigid it also cools the leaves by evaporation and it transports dissolved minerals around the plant.

A root hair cells function is to take in the water needed. They hae a large permanent vacuole which affects the movement of water from the soil across the root hair cell. 

Incase you wanted to know this a root hair cell is always positioned close to the xylem tissue which carries water up to the rest of the cell.
