Water passes from the soil to the root hair cell’s cytoplasm by osmosis. This happens because the water in the soil has a higher water potential than the root hair cell cytoplasm. Root hair cells have a large surface area for absorption of water and to speed up osmosis.
Plants absorb water through their entire surface – roots, stems and leaves. However, the majority of water is absorbed by root hairs. Root hairs are thin-walled uni-cellular outgrowths of epidermis. They are in close contact with the thin film of water surrounding the soil particles.Water's importance to plants stems from its central role in growth and photosynthesis, and the distribution of organic and inorganic molecules. Despite this dependence, plants retain less than 5% of the water absorbed by roots for cell expansion and plant growth.
