Sunlight

Vedclass · Answer

(A) Transpiration is the process of water loss from the aerial parts of plants. $A$. Sunlight: Increases temperature and triggers stomatal opening,which increases transpiration. $B$. Darkness: Causes stomata to close,which decreases transpiration. $C$. High humidity: Reduces the water potential gradient between the leaf interior and the atmosphere,decreasing transpiration. $D$. High speed winds: While wind can increase transpiration by removing the boundary layer,sunlight is the primary factor that directly influences the physiological opening of stomata. However,in the context of standard biology questions,sunlight is the most significant factor that promotes transpiration by opening stomata.
