Xylem serves as a conduit for the movement of water, minerals and phytohormones through a plant. Xylem is a vascular tissue, though its form varies from plant to plant.Continue Reading
Three types of cells compose a plant's xylem. The most important cells, called tracheary elements, are hollow structures that serve as the passageway for water and other small molecules. Tracheary elements occur in two different forms, tracheids and vessel elements. Though both types have some differences, their essential function is similar. Both are dead before the plant rotates them into use.
The other two types of xylem cells are the parenchyma cells and fiber cells. The essential purpose of both types is to provide structure and support for the tracheary elements. Additionally, they prevent the plant's weight from crushing the tracheary elements, which would halt the flow of water.
Xylem is the most abundant biological material on the planet. It is present in the stalks of plants and flowers and makes up the woody part of trees. Scientists suspect that xylem evolved around the time that plants began colonizing terrestrial habitats. Unlike ancient plants that evolved in aquatic or marine ecosystems, surrounded by water, terrestrial plants had to evolve to transport water throughout the plant's various structures.Learn more about Diagnostics & Imaging
According to CMG GardenNotes, the function of root hairs is to help the plant absorb water and minerals from the soil. The root hairs are thin, hair-like extensions of individual cells in the epidermis of the roots, which greatly increase the surface area of the cells.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 function of the cambium is to produce layers of phloem and xylem in a woody plant, thereby increasing the diameter of the stem. It is a thin layer of tissue that lies between the bark and the wood of a stem, and it is most active in woody plants.Full Answer >
Xylem is a type of vascular tissue that is responsible for moving water through a plant from its roots to its leaves. Columns of xylem tissue begin in the root hairs and rise all the way up through the leaves of a plant.Full Answer >
