How is root hair well adapted?

1.Osmosis is very important in root hair cells. Providing that the soil is moist, it is possible for water to enter the root hair by osmosis. (See the Osmosis Page if you have forgotten about this.)

2.Water passes from a region of high water concentration (wet soil) through a semi-permeable membrane (the cell membrane) to a region of lower water concentration (the cytoplasm). This makes the cell turgid.

3.As these cells develop they absorb water by osmosis and the hair can be pushed between soil particles.

4.The most important thing to remember about root hairs is that they increase the surface area between the root and the soil: this is necessary for the absorption of water and mineral salts.

All the best to you ! :D Hope this helped
