In order to carry out photosynthesis, the stomata must be open to allow CO2 to enter the leaves, and this results in the loss of water through transpiration. The movement of water from the roots to the stomata is partially a result of changes in water potential. Which of the following correctly describe(s) factors that affect transpiration in plants? a. Open stomata provide a pathway for CO2 to enter the leaf and for water to exit.
b. Water is pulled from the roots to the leaves by transpiration, moving from regions where the water potential is higher to where water potential is lower.
c. The water potential surrounding leaves in a humid area is lower than in leaves exposed to windy conditions.
d. In most plants, the highest rate of transpiration occurs when the rate of photosynthesis is highest.
e. Under humid conditions, the rate of transpiration will be higher than under windy conditions.
f. Under dry conditions, many plants close their stomata to minimize water loss.
