write three differences between xylem and pholem tissues of plants? (pls help yaar)
Answers
Explanation:
ylem 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
Answer:
xylem
* xylem transports water and minerals in upward direction.
* The movement of water through xylem is due to the suction force that is caused due to the continuous evaporation of water from leaves
* xylem transports only in one direction.
phloem
* phloem transports food material
* movement of food through the phloem tissue is carried by using ATP
* phloem transport food in both directions according to the need of the plants.
