Respuesta :
The only way for gases to diffuse in and out of the leaf is through small openings on the bottom of the leaf, the stomata.
The outer layers of cells on the underside of a leaf work to gather carbon dioxide by the utilization of stomata.
What are Stomata?
Stomata may be defined as the presence of tiny pores in the epidermis of the leaf or stem of the plant. The fundamental function of this structure is to regulate the amount of gas exchange.
A massive amount of gaseous exchange takes place in the leaves through these pores for the purpose of photosynthesis.
The opening and closing of these stomata are regulated by the guard cells. In order to prevent water loss through such pores, plants are required to close such pores during mid-day.
Therefore, the outer layers of cells on the underside of a leaf work to gather carbon dioxide by the utilization of stomata.
