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.
- Therefore plants living in this area open the stomata during the night to obtain Carbon dioxide.
- This checks the loss of water through transpiration and provides the carbon dioxide for photosynthesis.
