Question

Design an experiment to demonstrate the transpiration process.

Answer 1

Following the experiment can be performed to demonstrate transpiration in a plant:

1. Place a healthy growing plant on a horizontal and plane slab in the sun.
2. Place a glass bell jar over the potted plant and seal its end to the slab by applying vaseline at its edges.
3. Allow the set-up to remain in the sun for some time.
4. Observe the presence of water droplets on the inner surface of the glass bell jar.
5. This collection of water droplets is indicative of transpiration.
