The components that make up xylem tissue, essential for water transport and support in plants:
1. Tracheary Elements:
– Tracheids: These elongated cells with tapered ends transport water and minerals in gymnosperms and various vascular plants.
– Vessel Elements: Shorter and wider cells with openings at their ends, forming vessels in angiosperms for more efficient water conduction.

2. Xylem Parenchyma: Living cells supporting xylem function by storing starch, oils, and providing nourishment to neighboring cells.

3. Xylem Fibers: Elongated cells with thick walls offering structural support to the xylem, contributing to plant stability and strength.

4. Xylem Ray Cells (Ray Parenchyma): Horizontal, thin-walled cells extending from the center of stems or roots, aiding lateral conduction of water and nutrients and providing storage capacity.

These elements collaborate within the xylem tissue, forming a network that efficiently transports water and nutrients from roots to the rest of the plant while offering mechanical support and storage capabilities.
