Plants have evolved various adaptations to survive in arid environments. Some common adaptations include:
-
Reduced leaf surface area: Plants in arid environments often have smaller or fewer leaves to reduce water loss through transpiration.
-
Deep root systems: Plants develop deep root systems to tap into groundwater sources or reach deeper soil layers where moisture is available.
-
Succulent tissues: Some plants have succulent tissues that can store water, allowing them to survive periods of drought.
-
Thick cuticle: A thick waxy cuticle on leaves helps to reduce water loss through evaporation.
-
CAM photosynthesis: Some plants, like cacti, use Crassulacean Acid Metabolism (CAM) photosynthesis, which allows them to open their stomata at night to reduce water loss during the day.
These adaptations help plants to conserve water and thrive in arid environments.
