Question

describe the following experiments with diagrams
(1) to prove that plants give off water vapour in the process of transpiration ​

Answer 1

Explanation:

The following experiment proves that plants transpire:

1. one developing plant

2.clear plastic packs

3.tape

Methodology:

1. Place one sandwich pack more than one leaf.

2. Secure the pack on the stem with the tape.

3. Place the plant in the daylight for a few hours. (On the off chance that you are utilizing a plant from your garden, make sure to pick one that will be in the daylight for something like three hours.) Control

4. Fill the second sack with air without blowing into the pack.

5. Secure the sack a similar way you did the primary pack.

6. Place the second pack close to the plant you are utilizing to test your theory.

Result:

The droplets of water will appear on the inner face of the plastic bag. This shows that the water is lost from the leaves.

Answer 2

The process of evaporation of water from the surface of leaves via stomata is known as Transpiration.

Explanation:

• The Bell jar experiment can explain the phenomenon of transpiration.

• Requirements:

1. A bell jar is required.
2. Potted plant that has been well-watered
3. Sheets of rubber
4. Plate made of glass

• Procedure:

1. Cover the potted plant with the rubber sheet after it has been well watered. The plant's aerial parts should be left uncovered.
2. Cover the plant with the bell jar and place it on the glass plate.
3. Prepare a similar setup in the second bell jar, but without the plant.
4. Allow the apparatus to sit in the sun for a while.

• Observations: Water drops appear inside the walls of the bell jar with the potted plant, but none appear in the bell jar without the potted plant. This proves that plants give off water vapor in the process of transpiration.
