Root hair cell are dermal cells found on the roots of many vascular plants.
Their job is to provide a greater surface area for water absorption.
As transpiration pulls water up to the leaves, root hair cells have to absorb large amounts of water. The process by which root dermal cells take in water is osmosis. In order to diffuse large amounts of water, a cell obviously needs a large surface area. The root hair cells provide this needed extra surface area to absorb large amounts of water.

Where is water absorbed in plants?
water is absorbed through the roots of the plants. they need it to process theyre own food
Where in a plant would you find a root hair cell?
If one looks at the smallest roots plants have (on a mature plant), or on the root tip of a newly sprouting seed, one will see tiny little hair-like structures. You might need a magnifying glass to see them, because they are so small. These are the root hairs. They usually look like a fuze on the outside of these little roots. There is a single layer of cells covering the outside of these small roots, which is called the epidermis. These cells have a thin outside layer called the cell wall. These single cells of the epidermis produce an extension off of this outside cell wall that is long and thin. This is the root hair. As the root continues to grow, new cells in the epidermis start producing new root hairs, while older root hairs start to disappear. The root hair is not a single cell by itself, but rather a long, thin extension of the epidermal cell. It is used by the plant to increase the total surface area of the epidermal cells, which are use by the plant to absorb water and nutrients from the soil.
Why do pitcher plants have a smooth slippery surface with downward pointing hairs?
To trap insects for food. Slippery so they can not get a grip and downward pointing hairs to make climbing out difficult.
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
Which section of the root has root hairs?
the root hairs are located in the region above the root tip.
How many root hairs are there on each root?
one thousand root hairs are in a tree
Are tap roots the same as root hairs?
no tap roots are not the same as root hairs, root hairs are more of fibrous roots, on a plant there can only be one major tap root yet there can be many root hairs.
Is epidermis present in root hairs?
is epidrmis present in root hairs
Which are the single thread-like cells on the root epidermis?
Root Hairs
Are Root hairs are found mostly on the stomata.?
No root hairs are not found on the stomata.
Describe the appearance of the root hairs?
root hairs are basically separated to each other...they are fine like hairs
Explain are root hairs found all over a root?
Root hairs are found on the tips of the roots.
Why does the root need root hairs for the uptake of water and mineral?
because absorption of water takes place by root hairs in the root
Why are root hairs so important?
the root hairs get the food that the plant needs underground.
Why does the root need hairs for the uptake of water and minerals?
because absorption of water takes place by root hairs in the root
Do root hairs allow water to enter the root of a plant by germination?
No, water enters the root hairs by the process of osmosis
