Plants living in dry areas face conflict.
EXPLANATION:
- Since they live in dry areas they will undergo more transpiration.
-  If they open stomata during the day there will be excessive loss of water vapor that will result in their death.

- This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.
