What are some unique adaptations of desert plants?

Transcript

Desert plants have developed unique adaptations to survive in harsh conditions. For instance, many have deep root systems that allow them to access underground water sources, while others possess small leaves or no leaves at all to minimize water loss through transpiration^[1][3]. Some, like cacti and succulents, store water in thick, fleshy stems and have a waxy coating to reduce evaporation^[4][6]. Additionally, many desert plants use CAM photosynthesis, which allows them to absorb carbon dioxide at night to conserve water during the day^[1][4].
