Vedclass · Answer

(A) Stomata are specialized pores found in the epidermis of leaves and other green parts of plants. They play a crucial role in gaseous exchange ($CO_2$ and $O_2$) and transpiration. In most plants,stomata open during the daytime to facilitate the uptake of $CO_2$ required for photosynthesis and to release $O_2$ produced as a byproduct. This opening is regulated by the turgor pressure of guard cells.
