Tracheids are elongated or tube like cells with thick and lignified walls and tapering ends.
Vessel is a long cylindrical tube-like structure made up of many cells called vessel members, each with lignified walls and a large central cavity.
Xylem fibres have highly thickened walls and obliterated central lumens.
Xylem parenchyma cells are living and thin-walled, and their cell walls are made up of cellulose.
