(iii) Why is oil placed, over water ? (iv) What do we observe with regard to the level of water when this set up is placed in (1) bright sunlight (2) humid conditions (3) windy day ? (v) Mention any three adaptations found in plants to overcome the process mentioned in (ii) above.
Answer» (i) Transpiration (ii) Is the process of lpss of water in the form of vapour from the aerial parts of the plant. (iii) Oil placed over water to prevent direct evaporation of water. (iv) 1. In bright sunlight — The level of water will fall faster. 2. In humid condition — The level of water will fall very slowly. 3. On windy day — The level of water falls faster. (v) To reduce the rate of transpiration the plants adapts certain modefications. 1. The cuticle is very thick. 2. The leaves are absent or reduced to spines. 3. Stomata are covered by hair or Stomata located in pits.
