A root hair cell in a plant absorbs minerals that have been dissolved in water. They allow a plant to absorb these minerals by increasing the surface area; this is extremely beneficial to plants that are in dry areas.Continue Reading
The root hair cells are delicate structures on the root of a plant which live only two to three weeks. These cells constantly form at the top of the root of the plant, so as others die, new ones take their place. This allows the root hair coverage to remain the same despite root hairs constantly dying.
The root hairs vary in size, but the lengths range in diameter from about 5 to 17 micrometers and their lengths range from about 80 to 1,500 micrometers. Root hair cells are invisible to the naked eye, but can be seen with the assistance of a microscope. The root hair cells collect nutrients from the water as well as water itself from the soil. They then carry these nutrients and water up to the rest of the plant by way of the plant's roots. The root hairs secrete acids. These acids assist solubilizing minerals into ionic form; this makes the minerals easier to carry and transport through the roots of the plant.Learn more about Biology
The main function of a plant root is to absorb water and minerals from the soil for the plant to use. Roots also anchor plants into the ground, offering them support and keeping them from washing or blowing away. In some plants, such as carrots, roots store carbohydrates that the plant has made through photosynthesis for later use.Full Answer >
The main function of xylem cells is to carry water and soluble minerals from the root to the leaves of a plant. However, a secondary function of xylem tissue is to provide support for the plant. Xylem is present in vascular plants and is made up of different types cells, such as tracheids, fibers and parenchyma.Full Answer >
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. 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. These plant cells are essential to obtaining water from the ground for photosynthesis.Full Answer >
Chlorophyll’s function in plants is to absorb light and transfer it through the plant during photosynthesis. The chlorophyll in a plant is found on the thylakoids in the chloroplasts.Full Answer >
