The plant known for its ability to grow in desert conditions is the cactus, specifically the members of the family Cactaceae. Cacti have evolved unique adaptations to survive arid climates, including thick, fleshy stems that store water, spines that reduce water loss and provide some protection from herbivores, and shallow but extensive root systems that efficiently capture moisture from rainfall. Some species, like the saguaro cactus, can endure extreme temperatures and thrive in harsh desert environments. Cacti are not only important for their ecological roles, but they also hold cultural significance and can be found in landscaping and gardening.
