Question

Difference between xylem and phloem transport 0

Answer 1

Xylem :

It helps in transportation of water and mineral from root to leaves.

The movement is unidirectional.

The major component are xylem parenchyma, xylem fibre, tracheids and vessels.

Physical pressures like root pressure and transpirational pull causes upward movement.

Phloem:

It helps in movement of food.

Movement is in all directions .

Components of phloem are phloem parenchyma, phloem fibre, sieve tubes and companion cells.

The movement is by drawing energy from ATP.

Answer 2

★ Xylem...✒

• Xylem consists of tracheids, vessels, xylem parenchyma and xylem fibres.

• Xylem mainly consists of dead cells (except the xylem parenchyma).

• It conducts water and minerals from roots to aerial parts of the plant.

★ Phloem...✒

• Phloem is made up of sieve tubes, companion cells, phloem fibres and the phloem parenchyma.

• Phloem mainly consists of living cells (except phloem fibres).

• It translocates food prepared by the plant from the leaves to storage organs and growing parts of the body.
