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
How many root hairs are there on each root?
one thousand root hairs are in a tree
Is epidermis present in root hairs?
is epidrmis present in root hairs
Are Root hairs are found mostly on the stomata.?
No root hairs are not found on the stomata.
Which section of the root has root hairs?
The region of the root where root hairs are located is called the root hair zone. It is found just behind the root tip in the zone of maturation where new cells differentiate into root hairs to absorb water and nutrients from the soil.
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.
Are tap roots the same as root hairs?
No, tap roots and root hairs are not the same. Tap roots are the main root of a plant that grows straight down, while root hairs are tiny, hair-like extensions that grow from the surface of roots and are responsible for nutrient absorption.
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
Which are the single thread-like cells on the root epidermis?
Root hairs are the single thread-like cells that are found on the root epidermis. They increase the surface area of the root for absorption of water and nutrients from the soil.
How roots get food?
Root hairs on the root absorb water and minerals that are present in the soil. These are then transported from the root hairs to the root, and then throughout the rest of the plant.
Describe the appearance of the root hairs?
Root hairs are small, elongated structures that protrude from the outer surface of a root. They are typically colorless and extremely fine, giving them a thread-like appearance. Root hairs play a crucial role in absorbing water and nutrients from the soil.
What are root-like hairs that anchors plants?
root hairs is what they are called they are attached to the main and secondary root to help support the plant.
