Q

Its main function is to take part in conduction of water and mineral salt from root to upper region and provide mechanical support.

A

Vessels

17
Q

________ are thick walled, elongated, dead tubelike cells with lignified walls.

smaller than vessels

A

Tracheids

18
Q

The cell are thick walled and lignified.

They provide mechanical strength to xylem and as a whole to plant body, and also, they help vessel and tracheids in conduction.

A

Xylem fibre

19
Q

It is the only living component of xylem.

The cells are thin walled and made of cellulose.

Beside storing the food material, xylem parenchyma helps vessel and tracheids in the conduction.

A

Xylem parenchyma

20
Q

It conducts the prepared food from leaves to storage organs and growing regions.

A

Phloem

21
Q

thin walled, living and cell wall made of cellulose.

The main function of _____ _____ is conduction of prepared food from leaves to storage organ and growing region.

A

Sieve tube

22
Q

These are in closecommunication with sieve tube cell.
It helps sieve tube in conducting food material.

A

Companion cell

23
Q

are used for making ropes.
It is the only the dead component of phloem.
The cells are thick walled and lignified.
Besides providing mechanical strength to phloem, it helps sieve tube in conduction of food.

A

Bast/phloem fibre

24
Q

The cells are living, thin walled and cell wall made up of cellulose.

Beside storing food material, it help sieve tube in conduction of food.

A

Phloem parenchyma
