Root Hair Cell Structure

They also allow a plant to take in the minerals it needs to survive.

Root hair cell structure. The root hairs bearing cells are smaller cells than other cells. The root hair cells are delicate structures on the root of a plant which live only two to three weeks. A root hair cells main function is to basically absorb water to hydrate the structure. Energy from the sun is eventually used to convert water into hydrogen and oxygen.

So basically a root hair cells structure helps do this because it s very long and thin which starts. Root hair cells are specialised to perform a specific function. The function of the root hair cell is to obtain water from the ground and transport this to the xylem. Like other root cells it has a thick cell wall huge central vacuole and is separated from other root cells by a thin layer of cytoplasm.

Their structure allows the plant to absorb more water. Root hairs increase the absorptive surface of the epidermal cells. Plants absorb water from the soil by osmosis. These cells are located underground.

These cells constantly form at the top of the root of the plant so as others die new ones take their place. Root hair cells are adapted for this by having a large surface area to speed up osmosis. How is the root hair cell adapted to its function. The root hairs are where most water absorption happens.

Root hairs are tubular extensions of the outer walls of the epidermal cells. This allows the root hair coverage to remain the same despite root hairs constantly dying. A root hair or absorbent hair the rhizoid of a vascular plant is a tubular outgrowth of a trichoblast a hair forming cell on the epidermis of a plant root as they are lateral extensions of a single cell and only rarely branched they are visible to the naked eye and light microscope. The structure of the roots the water absorbed by the root hair cells passes through the plant in xylem tubes and eventually reaches the leaves.

A thin layer of cuticle is also present on some epidermal cells. They are long and thin so they can penetrate between soil particles and they have a large surface area for absorption of water. The structure of a root hair cell differs from other root cells in that it has a long thin extension supported by the central vacuole which greatly increases its surface area.
