1.	Given alongside is an experimental set up to study a particular process:(i) Name the process being studied. (ii) Explain the process named in (i) above. (iii) Why is the pot covered with a plastic sheet ? (iv) Mention one way in which this process is beneficial to the plant. (v) Suggest a suitable control for this experiment.
Answer» (i) Transpiration. (ii) ‘Loss of water as water vapour from the aerial parts of the plant is called as transpiration’. (iii) Covering the pot with a plastic sheet would prevent the escape of water vapour from the pot. (iv) Transpiration helps in the ascent of sap by producing a suction force acting from the top of a plant. (v) A similar empty plastic sheet with its mouth tied, with no potted plant kept in sunlight will show no drops of water.
