Root Hair Cell Structure Related To Function

The root hair cells are delicate structures on the root of a plant which live only two to three weeks.

Root hair cell structure related to function. Cell maturation root hair zone just above the region of cell elongation is where the cells mature they differentiate becoming specialized to perform specific functions. The root hairs are where most water absorption happens. The epidermal cells in this region have root hairs. A root hair cells main function is to basically absorb water to hydrate the structure.

They are long and thin so they can penetrate between soil particles and they have a large surface area for absorption of water. This allows more active transport of mineral ions to take place so the plant is able to take in as many important mineral ions as possible e g. This allows the root hair coverage to remain the same despite root hairs constantly dying. How is a root hair cell specialised to its function.

They are found only in the region of maturation of the root. A root hair cells main function is to basically absorb water to hydrate the structure. So basically a root hair cells structure helps do this because it s very long and thin which starts. 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.

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. For instance some cells become xylem cells some become phloem cells and some become cortical cortex cells. Root hair cells have a very large surface area due to them being very long and having hair like projections.
