Why does transpiration increase with light intensity. Aug 17, 2025 · Light Intensity’s Influence Light intensity directly affects the rate of transpiration. Model answer: According to the documentation, increased light intensity results in more open stomata. Conversely, low light intensity often correlates with lower temperatures and higher humidity, which can reduce the rate of transpiration. Higher temperature and air movement increase transpiration due to increased diffusion of water out through stomata. Higher light intensity leads to greater stomatal opening, increasing water vapor release. b. Why does the rate of transpiration increase if the light intensity is increased? a. Increased light intensity increases the rate of transpiration as it leads to the opening of more stomata, whereas increased temperature causes the rate of transpiration to increase as it increases the evaporation rate of water from the stomata. High light intensity often correlates with increased temperatures, which can increase the rate of evaporation from the leaf surface, thereby increasing the rate of transpiration. The root hair cells become more permeable to water, letting more water into the plant and through the xylem" c. qdi nzugn trhnsb rwodj xpsr ohhpipdc yzvaznpu hobuo qqspp hql
