Question

what is xylem and phloem.​

Answer 1

The vascular system is comprised of two main types of tissue: the xylem and the phloem. The xylem distributes water and dissolved minerals upward through the plant, from the roots to the leaves. The phloem carries food downward from the leaves to the roots.

Phloem and xylem are closely associated and are usually found right next to one another. One xylem and one phloem are known as a 'vascular bundle' and most plants have multiple vascular bundles running the length of their leaves, stems, and roots.

Answer 2

Answer:

what is xylem and phloem.

Xylem

• Xylem is the complex tissue of plants, responsible for transporting water and other nutrients to the plants.
• Xylem consists of dead cells (parenchyma is the only living cells present in the xylem).
• They comprise of xylem vessels, fibre and tracheids
• Xylem is located in the centre of the vascular bundle, deep in the plant
• Their movement is unidirectional.
• Xylem transports only minerals and waters from the roots

Phloem

• Phloem is living tissue, responsible for transporting food and other organic materials
• Pholem mainly contains living cells (fibres are the only dead cells in the phloem).
• They comprise of phloem fibres, sieve tubes, sieve cells, phloem parenchyma and companion cells.
• Phloem is located on the outer side of the vascular bundle.
• Their movement is bidirectional.

• Phloem transports food materials that are prepared by the green parts of the plants to other parts of the plant.
