Cacti have several structural adaptations, including thick, fleshy stems that store water and a waxy coating to reduce moisture loss. Their spines serve as a defense mechanism against herbivores while also minimizing water loss by reducing airflow around the plant. Behaviorally, cacti are adapted to their arid environments by opening their stomata at night to take in carbon dioxide, a process known as CAM photosynthesis, which helps conserve water during the hot daytime.
