$\begin{array}{cc}ColumnI& ColumnII\\ A.Xylemvessels& Perforatedplates\\ B.Xylemtracheids& Chisel-likeends\\ C.Xylemfibre& Obliteratedlumen\\ D.Xylemparenchyma& Storefoodmaterials\end{array}$
Xylem vessels are made up of dead cylindrical cells joined end-to-end. These cells have perforated end walls called perforation plates, which are for easy passage of water and minerals. Tracheids are long dead cells with chisel-like ends. The function of xylem parenchyma is to store food materials and to conduct water and minerals sideways. Xylem fibres are cells present in xylem for mechanical support. These cells are long, have thick cell walls and have obliterated lumens.
