The is a waxy coating that minimizes water loss from the aerial parts of a plant.

The waxy coating that minimizes water loss from the aerial parts of a plant is called the cuticle. The cuticle is a protective layer composed primarily of cutin, a type of lipid, and it plays a crucial role in reducing evaporation and preventing dehydration in plants. This adaptation is particularly vital for terrestrial plants that are exposed to varying environmental conditions. The cuticle's effectiveness in minimizing water loss allows plants to thrive in diverse habitats, including arid ecosystems where water retention is essential for survival. Overall, the cuticle is an important component of a plant's defense against desiccation and environmental stress.
