प्रश्न
Suppose you have a rose plant growing in a pot, how will you demonstrate transpiration in it?
उत्तर
Tie a plastic bag over leaves of rose plant and place in sunlight. After a few hours, we see water condensing inside the plastic bag. This is due to loss of water in the form of water vapour, which condenses into water. This is due to transpiration.
