The Cactaceae family, commonly known as cacti, consists of succulent plants primarily found in arid regions of the Americas. These plants are characterized by their thick, fleshy stems that store water, allowing them to survive in dry environments. Cacti often have spines instead of leaves, which help reduce water loss and provide protection from herbivores. Cacti exhibit a wide variety of shapes and sizes, ranging from small, round species to tall, columnar forms. Many cacti produce vibrant flowers that can attract pollinators like bees and birds. Some well-known genera within the Cactaceae family include Saguaro, Opuntia, and Echinocactus.
