Take two small pots of approximately the same size and having the same amount of soil. One should have a plant in it. Place a stick of the same height as the plant in the other pot.
Cover the soil in both pots with a plastic sheet so that moisture cannot escape by evaporation.
Cover both sets, one with the plant and the other with the stick, with plastic sheets and place in bright sunlight for half an hour.
Do you observe any difference in the two cases?
- ✅ Answer: Yes. In the pot with plant, water droplets are found in the plastic sheet. It is due to the condensation of water vapour released by transpiration. In other pot, water droplets are not formed.
