Which Action Allows a Plant to Conserve Water

Question

Which action allows a plant to conserve water?
A) increasing photosynthesis during the day
B) opening stomata only at night
C) possessing large leaves
D) developing wide vessel elements

Accepted Answer

Opening stomata only at night allows a plant to conserve water as transpiration occurs during the day when temperatures are high and air is drier, making it more difficult for plants to retain water. By closing stomata during the day, water loss through transpiration is minimized, conserving water.
