Question

how can you prove that water is transported through the xylem

Answer 1

A leafy green shoot of Balsam plant with a transparent stem is placed in Eosine solution (It is red dye resulting from the action of. bromine).After sometime red streaks appear in the stem and veins of leaves become red.If a transverse section is cut through the root stem and leaf, the tissue that has been stained is xylem tissue.This shows that water moves up the root into the stem and leaves in the xylem tracheids and vessels.The other tissues remain in the same colour.
Conclusion : The xylem tissue is the tissue responsible for the upward movement of water through the plant.

Answer 2

Answer :-

To prove that the water is transported through the xylem a plant. Set Apparatus as shown.

i. Procedure :

Take a leafy green shoot of Balsam plant with a transparent stem and place it in Eosin solution (It is red dye resulting from the action of. bromine).

ii. After sometime red streaks appear in the stem and veins of leaves become red.

iii. If a transverse section is cut through the root stem and leaf, the tissue that has been stained is xylem tissue.

iv. This shows that water moves up the root into the stem and leaves in the xylem tracheid and vessels.

v. The other tissues remain in the same colour.

Conclusion :- The xylem tissue is the conducting tissue that conducts water from roots to the other parts of plants. .
