Xylem is a plant tissue that is vascular in nature and assists in the movement and transport of water and minerals from the lower to upper regions of the plant.
It conducts passive transport and the phenomenon that drive water flow in xylem are pressure flow, transpirational pull, and root pressure.
It offers physical support to the plant and prevents the plant from bending and falling.
The xylem tissue consists of four cell types - xylem vessels, fibers, xylem parenchyma, and tracheids.
Gymnosperms are seed-producing plants that don't bear flowers.
Xylem tissues are present in gymnosperms but lack xylem vessels as they do not produce flowers.
