Answer:
components are tracheids, vessels, xylem parenchyma and xylem fibres.
Explanation:
Tracheids: Dead, tube-like cells with a tapering end. They are present mostly in gymnosperm and lower angiosperm. They have a thick lignified wall and lack protoplasm. Their main function is water and mineral transportation
Vessels: They are present in angiosperms. These are a long cylindrical structure having tube-like appearance. The walls are lignified and have a large central cavity. They are also dead and lack protoplasm. They have many cells called vessel members which are interconnected through a perforation in common walls. Mostly involved in the conduction of water, minerals and give mechanical strength to the plant
Xylem Fibre: Dead cell with lignified walls and a central lumen. Involved in water transportation and providing mechanical support
Xylem Parenchyma: Only living cells of xylem and store starch and fat. They assist in the short distance transportation of water
