what is the difference between xylem and phloem |
|
Answer» Main difference is that Xylem transport water from roots to other part of plant but phloem transport food material from leaves to other part of plant \tXylemPhloemXylem tissues are tubular shaped structure, with the absence of cross walls. This tissue resembles the shape of a star.Phloem tissues are elongated, tubular shaped structures that include thin sieve tubes with walls.Xylem occupies the centre of the vascular bundle.Phloem is located on the outer side of the vascular bundle.Xylem fibres are smaller.Phloem fibres are larger.They are present in leaves, stems, and roots.They are present in leaves, roots, stems but transports and grow in fruits seeds and roots.These tissues move in a Unidirectional. (only in one direction – upward direction)These tissues move in a Bidirectional. (both ways – up and down)They live with hollow dead cells.They live with cytoplasm without the nucleus.The total amount of xylem tissue is more.The total amount of phloem tissue is less.It consists of tracheids, vessel elements, xylem parenchyma, xylem sclerenchyma and xylem fibres.It consists of four elements: sieve tubes, companion cells, phloem fibres, bast fibres, intermediary cells and the phloem parenchyma\t |
