Question

Foliar transpiration includes _______.

• A. Stomatal transpiration
• B. Cuticular transpiration
• C. Both a $\&$ b
• D. Lenticular transpiration.

Answer 1

The correct option is C Both a $\&$ b

Transpiration occurs mostly through stomata located on leaves. It also occurs through cuticle and lenticels. Foliar transpiration is the term given to transpiration that occur from the leaf surfaces, which includes the loss of water vapor through stomata and cuticles. Lenticels being present mainly in the stems and branches do not form a part of foliar transpiration.
