Question

Meaning , definition and difference between xylem and phloem

Answer 1

hey...here is ur answer...
____________________________________________________

xylem:
xylem (Greek xylos = wood......xylem is the water and minerals.. conducting tissue.....xylem gives mechanical strength to the plant body...

Phloem : phloem is the chief food conducting tissue of vascular plants it is regarded as living conducting tissue responsible for translocation of organic solutes ...

NOW, difference between xylem and phloem...

xylem :

1) it conducts water and inorganic solutes in vascular plants..

2) conduction mostly ocuurs in one direction( I.e upward)

3) conducting channels( tracheary elements) are tracheids and vessels...

4) xylem provide mechanical strength also....

5) tracheids , vessels and xylem fibres are dead and only xylem parenchyma is living....

Phloem :

1) it conducts organic solutes in vascular plants ...

2) conduction may occur in both directions , i.e ,upward and downward....

3) conducting channels are sieve tubes...

4) Sieve tubes, companion cells and phloem parenchyma are living and only pheolm fibres are dead....

5) phloem does not provide mechanical strength....

HOPE IT HELPS YOU...!✌

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.
