Science > Grade 1 > Plants > How plants adapt. Adaptation in a population of living things happens as a result of an adaptive trait. It is a misconception that cacti actually live in true deserts where the ground is all sand. These shapes also reduce the heating effects of the sun. In most cases, they are yellow or brown and only produce spines or flowers for a few years before they become inactive. Ask the class to identify ways the cactus adapts. To survive in harsh dry, hot desert climates, the prickly pear cactus has adapted successful features such as the water-storing capability of its thick, fleshy leaf pads and the sharp spikes on those pads that deter animals from eating it. Haworthia is another genus that often exhibits this unusual succulent adaptation. Would you want to eat something that is prickly?
