Question

State whether the following statements are true or false .
Transpiration takes place only through stomata in terrestrial plants.

• A. True
• B. False

Answer 1

The correct option is B False

Transpiration can vary according to the type of structure involved. It is of four types:

1. Stomatal transpiration: Occurs through stomata. It is responsible for 50-97% of total transpiration.

2. Cuticular transpiration: Occurs through cuticle (a waxy layer that covers the epidermis of leaves and stems). Contributes 3-10% of the total transpiration.

3. Lenticular transpiration: Occurs through lenticels (aerating pores in the cork of woody stems). insignificant contribution to water loss.

4. Bark transpiration: Occurs through the bark of woody stem. Contributes to 1% of total transpiration.

So, the given statement is false.
