Detailed explanation-1: -Light intensity: The transpiration rate is increased due to the increase in light intensity. During daytime in the sunlight, the rate of transpiration is faster. This is because the stomata remains open to allow the inward diffusion of carbon dioxide for photosynthesis.

Detailed explanation-2: -Light intensity is known to affect transpiration as well as other plant processes. Since the greater amount of transpirational water is lost during the day, the natural assumption is that with increased light intensity the transpirational curve would rise.

Detailed explanation-3: -When you increase the level of light, plants will photosynthesize more. But, if you have too much light, than the other 2 ingredients become limiting and photosynthesis can no longer increase with the level of light. When this occurs, leaves can experience sunburn damage.

Detailed explanation-4: -Light Intensity: Increasing the light intensity to which a plant is exposed is predicted to cause an increase in the rate of transpiration. Increasing light exposure will cause more stomata to open in order to facilitate photosynthetic gas exchange.

Detailed explanation-5: -Most of the water a plant loses is lost due to a natural process called transpiration. Plants have little pores (holes or openings) on the underside of their leaves, called stomata. Plants will absorb water through their roots and release water as vapor into the air through these stomata.
