(a)Xylem tissues are dead cells at maturity as they are hollow and do not havecytoplasm.(b)To transport water and mineral salts that are absorbed by the roots, to the stems andleaves.Adaptations:- The tissue is hollow to allow water transport..The walls have lignin to provide support and...
Xylem(from the Greek xylon, for wood) generally refers to the dead tubular cells that form an internal watervascular systemin plants. Although the term ‘wood’ is frequently used as a synonym for xylem in trees and shrubs, xylem is a complex tissue present in allvascular plants(also called...
Why is xylem described as a tissue?Vascular Tissue:Vascular plants contain vascular tissue. These tissues are phloem and xylem. They are found in vascular bundles. Phloem carries food and nutrients to the cells, whereas xylem transports water throughout the plant. ...

These are dead and are tube-like cells with a tapering end. They are found in the gymnosperm and angiosperm. These cells have a thick lignified cell wall and lack protoplasm. The main function they perform is water and mineral transportation.Figure 7: Structural components of xylem tissue. Cre...
Xylem sclerenchyma: They are dead cells that are fibrous in nature. They lack protoplast. They lie between the tracheids and xylem vessels. These are narrow cells and are elongated. Their walls are composed of lignin. Phloem Definition Phloem, which is also a complex tissue, belongs to the...
Xylem:Xylem is a complex tissue in plants that transports water, minerals, and nutrients from the roots to the other parts of the plant, primarily the leaves. It is composed of specialized cells called tracheids and vessel elements, which form long tubes or vessels for fluid movement. Xylem ...
