Answers
Xylem is the complex tissue of plants, responsible for transporting water and other nutrients to the plants. Phloem is living tissue, responsible for transporting food and other organic materials.
Contains Dead cells (parenchyma is the only living cells present in the xylem). Mainly contains living cells (fibers are the only dead cells in the phloem).
Comprises of Xylem vessels, fibre and tracheids. Phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells.
Found Xylem is located in the centre of the vascular bundle, deep in the plant. Phloem is located on the outer side of the vascular bundle.
Kind of movement Unidirectional. Bidirectional.
Role Xylem transports only minerals and waters from the roots. Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant.
Provide mechanical support. Does not provide mechanical support.
1) Phloem helps in transportation of food while Xylem helps in transportation of water.
2) The movement of Phloem is bidirectional while the movement of Xylem is unidirectional.
3) Xylem fibres are smaller while Phloem fibres are larger.
4) Xylem live with hollow dead cells while Phloem live with cytoplasm without nucleus.
5) Xylem forms vascular bundles with Phloem while Phloem forms vascular bundles with Xylem.
6) The total amount of Xylem tissue is more while the total amount of Phloem tissue is less.
