Solution

The correct option is C
The loss of water through aerial parts of the plant in the form of vapour is called transpiration. Transpiration can happen through cuticle, lenticel and stomata. Transpiration through stomata is called stomatal transpiration. Stomata are small pores found on the epidermis of the leaf.

Q. Identify the structure through which cuticular transpiration happens.

Q. Case: Transpiration is the evaporative loss of water by plants. It occurs mainly through the stomata in the leaves. Besides the loss of water vapour in transpiration, exchange of oxygen and carbon dioxide in the leaf also occurs through pores called stomata. Normally stomata remain open during the day and close at night.

Based on the above case answer the following question:

Water vapour comes out from the plant leaf through the stomatal opening. Through the same stomatal opening, carbon dioxide diffuses into the plant during photosynthesis. Reason out the above statements using one of the following options.
