Question

Explain transportation of water in plants? How does transpiration helps in water suction?​

Answer 1

Answer:

xylem helps in transportation of water in plants ,there are 4 types of xylem tissue

Answer 2

Explanation:

Xylem conducts water and mineral salts from the rots to the aerial parts of the plant.

1. It is made up of tracheids, vessels, xylem parenchyma and xylem fibres.
2. This tissue forms a tubular passage to transport water and mineral salts.

TRACHEIDS:

• These are the elongated dead cells with tapering ends. Their walls have thickenings with lateral pores. They provide mechanical strength and support to the plant in addition to conducting water upwards.

VESSELS:

• They are tube-like structures open at both ends. They are placed on above the other, to form long channels. Just like tracheids, they provide mechanical support to the plant and conduct water upwards.

XYLEM/WOOD PARENCHYMA:

• They are small, thick walled, living cells. They store food and also help to conduct water and mineral salts.

XYLEM SCLERENCHYMA/WOOD FIBRES:

• They are thick walled, narrow cells with tapering ends. They provide only mechanical support to the plant.
