One was revealed the fact that root hairs on plants roots are involved in the absorption of water and nutrient in the soil. These are then sent all over the plant. It is known that most of the uptake of water can be realized with the help of these structures, namely tiny hairs. They are long enough so as to filter in between the particles of the soil and the bacteria cannot penetrate through to the plants vascular system the xylem. Root hairs expand the root surface area so that nutrient acquisition is enhanced as the plant come into contact with friendly microorganisms. Their function is not restricted with sunlight as is with roots; therefore, root hairs do not have chloroplasts and do not perform photosynthesis.
