What a the function of the root hair?

Answer 1

The function of root hairs is to increase surface area for nutrient absorption which is vital for plant survival.

1) absorption of water and inorganic nutrients

2) anchoring of the plant body to the ground

3) function in storage of food and nutrients

4) in response to the concentration of nutrients, roots also synthesise cytokinin, which acts as a signal as to how fast the shoots can grow.

Answer 2

Root hairs are extremely important in water and nutrient uptake. Root hairs are ephemeral (shortlived) structures that have a high pay-off for the plant. The plant does not have to waste a lot of energy on producing them, but because of their high surface area they come in contact with a large volume of soil and therefore have a greater chance of accessing soil nutrients.

Answer 3

Tiny, hair-like outgrowth of some surface cells of plant roots that greatly increases the area available for the absorption of water and other materials such as minerals. It is a delicate structure, which survives for a few days only and does not develop into a root. Root hair cells are found just behind the root tip where they are continually being formed. They grow out into the soil for a few millimetres to produce the root hair. Each root hair is made of a single cell. At the root tip mitosis cell division is very active making new cells for growth to replace the root hair cells that die.

Answer 4

Root hairs increase the surface area of the root system, allowing for better absorption of water and nutrients from the soil. They also help anchor the plant in the soil and provide a direct pathway for the movement of water and minerals into the root.

Answer 5

Root hairs increase the surface area of the root, thereby increasing the amount of water and nutrients taken in by the plant.

Answer 6

They have a large surface area that helps to absorb water and minerals from the soil.

Answer 7

root hair is the cell of a root that aborbs water n minerals
