Answer 1

Answer:

Transpiration is the process of plants releasing water through their leaves (through pores called stomata). ... With this experiment, you can capture that water and make comparisons between leaves in the sun or shade, differing kinds of leaves, or even leaves that are on versus off the plant.

Explanation:

All you need are plastic bags, and a plant with leaves or needles. For guidance through a comparison of the transpiration rates of different types of leaves, check out our downloadable experiment guide. Or try your own creative transpiration experiment: compare different sized leaves, compare different color leaves, compare leaves in the sunlight versus the shade… the possibilities are endless

Answer 2

QUESTION :-

• Explain transpiration in the plants with an experiment.

ANSWER :-

→ Definition :-

Transpiration is the biological process by which water is lost in the form of water vapour from the aerial parts of the plants.

→ Process :-

Like all living organism, plants also require an excretory system to discharge excess water from their body. This process of elimination of excess water from the plant body is known as transpiration. It is generally the evaporation of water from the surface of the leaves.During the process of transpiration, water molecules in the plant tissues are removed from the aerial parts of the plants. Only a small amount of water absorbed by the plants is utilised in growth and development. The rest is eliminated in the form of transpiration.

Note :- Refer to first image for explanation.

Experiment :-

REQUIREMENTS:

• Bell jar

• Well watered potted plant

• Rubber sheet

• Glass plate

PROCEDURE:

•Take the well watered potted plant and cover it with the rubber sheet. The aerial parts of the plant should be left uncovered.

• Put the plant on the glass plate and cover with the bell jar.

• Prepare a same setup but without a plant in the second bell jar.

Take the well watered potted plant and cover it with the rubber sheet. The aerial parts of the plant should be left uncovered.

• Put the plant on the glass plate and cover with the bell jar.

• Prepare a same setup but without a plant in the second bell jar.

• Place the apparatus in sunlight for sometime.

OBSERVATIONS:

Water drops appear inside the walls of the bell jar containing potted plant whereas no water drops appear in the bell jar without a plant. This demonstrates that water is evaporated from the surface of leaves in presence of sunlight.
