3. On hot, dry days the leaves of trees will close their stomata in order to conserve water and reacta,) occurrence of transpiration, a process in which water is lost from plant leaves through the stomata. V conditions are hot and dry for a prolonged period of time, drought occurs. During times of extreme drought, trees that are not adapted to living in drought conditions will often rapidly shed their leave biologist is curious to know how this phenomenon affects the tree's ability to perform photosynthe Which of the following is a testable question relating photosynthesis to this phenomenon that a bio could investigate with an experiment? a. Do extreme drought conditions cause trees to conserve energy by losing their leaves? b. Do extreme drought conditions cause trees to lose their leaves due to a lack of raw materia for photosynthesis? Does the loss of leaves due to extreme drought cause trees to perform photosynthesis in c of the tree? d. Does the loss of leaves due to extreme drought cause the trees to perform cell respiratior photosynthesis?
