(A) Lenticel
(B) Cuticle
(C) Stoma
(D) Bark
Stoma is the organ of the plant where maximum transpiration occurs. Transpiration is the process through which living plants lose water as vapors from their aerial organs. Only a small portion (1-2%) of water absorbed is utilized by the plants; the remaining (98-99%) is lost to evaporation in the atmosphere.

Maximum Transpiration Occur in Stoma
Transpiration is a necessary evil, it is said by Curtis. The stomata are responsible for the most transpiration. A group of Stomas is known as Stomata in Plants.
There are three types of transpiration. They are explained below in detail.
- Stomatal transpiration occurs through stomata; between 80 and 90 percent of transpiration happens this way.
- Cuticular transpiration is the process through which water is lost from herbaceous leaves and stem cuticles. The waxy layer that covers the epidermis is known as the cuticle. It is where 9% of transpiration happens.
- Through lenticels, lenticular transpiration (small pores on the epidermis and stem of plants that are woody). It experiences the smallest amount of transpiration, ranging from 0.1 to 1%.
Succulent xerophytes have the highest transpiration rates. In mesophytes, transpiration is at its highest.
Summary:
Through which organ of the plant does the maximum transpiration occur? (A) Lenticel (B) Cuticle (C) Stoma (D) Bark
The plant’s stoma is where the most transpiration takes place. It is the pore on the surface of leaves in plants. With the help of a Stoma, plants take CO2 for the photosynthesis process. It is a mandatory process for plants.
