Which of the following is NOT a main site of transpiration?

Correct option is C

The correct answer is (C) Intracellular spaces.

•  Intracellular spaces are related to the gaps or spaces found between the cells of tissues in multicellular organisms.

Information Booster.

• The main site of transpiration in plants is the stomata on the leaves.

Cuticular transpiration:  

• Cuticular transpiration is a type of water loss that occurs through the cuticle, a waxy, protective layer covering the epidermis of plants. Although most transpiration occurs through stomata (stomatal transpiration), a smaller proportion takes place directly through the cuticle.
• Cuticular transpiration is particularly important when stomata are closed (e.g., at night or during drought stress) and contributes to a plant's overall water regulation.

Lenticular transpiration: 

• Lenticular transpiration refers to the loss of water in the form of vapor through lenticels, which are small, spongy openings in the bark of stems, branches, and other woody parts of plants.
• Lenticular transpiration is most noticeable in plants with prominent lenticels, such as mango, guava, or birch trees. It primarily occurs in older, woody parts of the plant where stomatal transpiration does not occur.
