Which adaptation would you expect to find in a desert plant?

The adaptation found in desert plants that is most critical for their survival is a waxy coating to prevent water loss. In desert environments, where water is scarce, plants must develop adaptations to minimize moisture loss from their tissues. The waxy coating, often referred to as a cuticle, serves as a protective barrier that helps reduce evaporative water loss. This adaptation allows desert plants to retain moisture, enabling them to survive in extreme temperatures and arid conditions.

While other adaptations, such as deep roots or the ability to follow the sun, may be beneficial in certain contexts, they do not address the direct challenge of water retention as effectively as the waxy coating does. This coating helps secure the necessary moisture for the plant's biological processes, making it essential for survival in a desert ecosystem.
