Over 1750 known species are grouped within this family, ranging from small, round structures to large, tree-like formations. Cacti are predominantly found in the [[Americas]], with their range extending from [[Patagonia]] in the south to parts of western [[Canada]] in the north. They are a defining component of the [[desert]] landscapes, particularly in the [[North American deserts|North American]] deserts, such as the Mojave and Sonoran.<br />
<br />
==Characteristics==<br />
Cacti are well adapted to survive in the desert. They have numerous adaptations such as [[photosynthesis]] through their stems, spines for protection against herbivores, and thick, fleshy parts to store water. Cacti's roots are generally shallow and spread out to capture as much moisture as possible from light rains. Their skin is thick and waxy to reduce water loss. The spines, which are modified leaves, provide shade and reduce air flow over the cactus surface, further reducing water loss.<br />
<br />
==Reproduction==<br />
Cacti can reproduce both sexually through [[flower]]s and asexually through [[offshoot]]s. Their flowers are often large and colorful to attract pollinators. Many species of cacti have a unique relationship with specific species of [[pollinator]]s, such as bees, bats, and birds, including the [[hummingbird]]. After pollination, cacti produce fruits that contain seeds. These fruits can be a food source for desert wildlife, aiding in the dispersal of the seeds.<br />
<br />
==Classification==<br />
The Cactaceae family is divided into several [[genus|genera]], which are further divided into numerous species. The family is primarily classified into two main subfamilies: [[Opuntioideae]], known for members like the prickly pear, and [[Cactoideae]], which includes the majority of cacti species such as the saguaro and the barrel cacti. Each genus and species has adaptations that suit their specific environmental niche.<br />
<br />
==Cultivation and Uses==<br />
Cacti are popular in [[horticulture]] for their unique shapes and flowers. They are often grown as ornamental plants both indoors and outdoors. Some species provide edible fruits, such as the prickly pear and dragon fruit, which are consumed around the world. Cacti have also been used traditionally by indigenous peoples for their medicinal properties and as building materials.<br />
<br />
==Conservation==<br />
Many cacti species are threatened by habitat loss, overcollection, and climate change. Conservation efforts include habitat protection, cultivation in [[botanical garden]]s, and laws regulating the collection and trade of wild cacti. The [[Convention on International Trade in Endangered Species of Wild Fauna and Flora]] (CITES) regulates the international trade of cacti to protect endangered species from overexploitation.<br />
