Question

Foliar transpiration

• A. Includes stomata and cuticular transpiration
• B. Does not occur
• C. Includes all type of transpiration
• D. Shows stomatal transpiration

Answer 1

The correct option is A Includes stomata and cuticular transpiration

The loss of water in the form of vapour from the aerial parts of the plant is referred to as transpiration.

Transpiration in plants is of three types-
a. Cuticular
b. Lenticular
c. Stomatal
Cuticular transpiration is the transpiration takes place through outer covering of the epidermis, called as cuticle.

Lenticular transpiration is the transpiration occurs through lenticels. Lenticels are regions on the bark of woody tree trunk having loosely arranged cells.

Stomatal transpiration is a transpiration occurs through stomata, which are minute openings on the epidermis of leaves and stems.

The transpiration occurs through foliar surface or surface of the leaves, known as foliar transpiration e.g., stomata and cuticles . Foliar transpiration accounts for over 90% of the total transpiration. Thus, the correct answer is option A.
