Answer: Plants have evolved various adaptations to prevent water loss and survive in different environments. Two of these adaptations include:
1. Waxy Cuticle
- Plants have a waxy cuticle on the outer surface of their leaves, stems, and other parts. This waxy layer helps to prevent water loss by reducing evaporation from the plant's surface.
- The waxy cuticle acts as a waterproof barrier, effectively sealing moisture inside the plant and protecting it from drying out. It also helps plants cope with dry and arid conditions by minimizing water loss through transpiration.
2. Stomatal Regulation
- Plants regulate water loss through tiny openings called stomata present on the surfaces of leaves and stems. These stomata can open and close to control the exchange of gases like oxygen and carbon dioxide, as well as water vapor.
- During hot and dry conditions, plants can close their stomata to reduce water loss through transpiration. By closing the stomata, plants conserve water while still allowing for essential gas exchange for photosynthesis.
These adaptations demonstrate how plants have evolved mechanisms to cope with varying environmental conditions and ensure their survival by minimizing water loss.
