Tip of root that is growing into the soil (area of mitosis)
|
Detailed explanation-1: -Root hairs are the small tubular extensions of the root surface which help in the absorption of water and minerals from the soil. It increases the surface area for absorption. More number of root hairs will increase the surface area and increase water absorption also.
Detailed explanation-2: -Root hairs collect water and minerals that are present in the soil. They also increase the surface area for absorption.
Detailed explanation-3: -Their distinctive lateral elongation increases the surface of exchange between the plant’s root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.
Detailed explanation-4: -Root hair cells improve plant water absorption by increasing root surface area to volume ratio which allows the root hair cell to take in more water. The large vacuole inside root hair cells makes this intake much more efficient.
Detailed explanation-5: -Root hairs form in the zone of differentiation and this is where they begin to poke out into the soil to absorb water and mineral nutrients. Root hairs greatly increase the root surface area and therefore increase the ability of a plant to absorb water and nutrients.
