Question

"Can heat absorption by leaves hinder leaf function? Explain your answer and describe ways in which leaves can dissipate absorbed heat."

Answer 1

Answer:

yes, heat obsorption hinder leaf function

Explanation:

yes, heat obsorption hinder leaf function

Photosynthesis inhibition is generally viewed as a important factor in heat stress. Usually the first method to be inhibited at elevated temperatures is net photosynthesis. As temperature increases above optimum, there is inhibition of gross photosynthesis as respiration and photorespiration rise. These three procedures combine to significantly reduce net photosynthesis during mild heat.

By raising the reflection of the leaf surface, the quantity of incident radiation absorbed by a leaf can be decreased.
