generally, root hairs are not the ones who absorb water, it is still a function of the root. the function of the root hair is to increase the absorptive capacity of the root by creating capillary.
CABaLLO:
Root hair cells are cells which have tubular extensions that arise from epidermal cells and greatly increase the rate at which water is absorbed by the plant. They provide a large surface area over which water can be absorbed. They also have a very thin membrane - and since diffusion is only effective over short distances this also helps absorption of water. The root hair cells also pump inorganic ions such as Na+ into the cell by active transport, creating a water potential gradient down which water can move by osmosis from the soil (where there is a higher water potential) to the root cell where there is a lower water potential.

How are root hair cells specialised?
it is layered and it grows, it helps the hair cell when providing a greater surface area for water absorption
What has a large surface area to help the cells absorb water quickly?
Root hair cell
How is a root hair cell good at its job?
Root hair cells are used in osmosis to transmit water and nutrients from the soil. These root hair cells reduce the loss of water and adapt to the large surface area and speeds up osmosis process.
How is a root hair cell adapted to perform its function?
They have root cells inside their roots to absorb water they are tough to stay in the ground. A root hair cells job is to provide water and nutrition for a plant. Root hair cells have to absorb large amounts of water. The process by which root cells take in water is osmosis. In order to take in large amounts of water, a cell needs a large surface area. Root cells, have a large surface area over which absorption of minerals and water can occur.
Does being turgid provide support for root hair cell?
Yes, when a cell is turgid it means that it is full of solvent, or in this case water, and provides for support. Plant cells have central vacuoles that are meant to store water and provide for the plant's support -- when a plant is droopy, it means that the plant isn't receiving enough water and its cells' central vacuoles are deprived of water, therefore unable to provide structural support. I can assume that this is the same for root hair cells. The opposite of a cell being turgid (meaning hard and full) is a cell being flaccid (empty, weak, flingy). The latter would not provide ANY support for the root hair cells, so my final answer is yes, being turgid does provide support for root hair cells.
Why respiration rates increase in root hair cells during the uptake of mineral ions?
due to active transport system
How does the presence of hair cells of roots enables effecient absorption of water?
They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.

How the presence of root hair cells on root enables the efficient absorption of water and minerals?
They develop a cytoplasmic hair-like elongation which increases its surface area for more absorption. It also has a large number of mitochondria which provides energy needed for the active uptake of minerals.

How many cells are there in a root hair?
there are about thousands of root hairs
What are the small hair like things that are on plant roots?
Root hairs - Absorptive unicellular extensions of epidermal cells of a root. These tiny, hair-like structures function as the major site of water and mineral uptake. Root hairs are extremely delicate and subject to desiccation. Root hairs are easily destroyed in transplanting.
What is the structure of root hair cells?
The root hair cells has a special structure to help it absorb water from the soil efficiently. 1. Elongated structure that protrudes out to the soil - This is to increase the surface area to volume ratio; thereby increasing the rate of uptake of water from the soil to the cell. 2. Large vacuole - The root hair cell has a large vacuole to maximize the amount of water capacity of the cell; thus, the cell is able to absorb and store more water. 3. Cell sap - The cell sap of the root hair cell has a lower water potential than the water in the soil. Thus, the water from the soil moves into the cell via osmosis.
What does the hair cells do?
it absorbs water and is a plant cell
What hair takes takes up water in a plant?
The roots of a plant are responsible for taking up water from the soil. Specifically, the tiny, hair-like structures called root hairs are the main site of water absorption. Root hairs increase the surface area of the roots, allowing for more efficient water uptake.
Function of root hair cell?
To absorb water and nutrients from the soil.
What is the adaptation of the hair root cell?
To speed up osmosis root hair cells have a large surface area. Root hair cells absorb water and minerals from surrounding soil.
