Gaseous exchange

Vedclass · Answer

(D) Stomata are small pores present on the surface of leaves and young stems. They perform two primary functions: $1$. $Gaseous$ $exchange$: They allow the entry of $CO_2$ and the exit of $O_2$ during photosynthesis and respiration. $2$. $Transpiration$: They facilitate the loss of water in the form of water vapor from the plant body. While both $B$ and $D$ are functions of stomata, in the context of general biological questions regarding the primary role of stomatal pores in plant physiology, 'Gaseous exchange' is the most fundamental process for survival. However, if the question implies a single best answer, 'Gaseous exchange' is the most comprehensive answer.
