differentiatr between Phloem and Xylem with at least three differences
Answers
Answer:
BASIS FOR COMPARISON XYLEM PHLOEM
Meaning 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.
Other features Xylem is the dead tissues at maturity, but no cell contents. Phloem is the living tissue, but not with the nucleus.
Xylem often constitutes the bulk of the plant body. Phloem forms a small part of the plant body.
In xylem, the conducting cells or tracheary cells are dead. In phloem, the conducting cells are living.
