Cacti
Cacti are a unique group of Plants that have adapted to survive in arid environments with limited Water availability. They are characterized by their thick, fleshy Stems that can store water, and their sharp Spines that help to reduce Transpiration. Cacti are native to the Americas, and are commonly found in Desert ecosystems. They have evolved a range of specialized features, including Crassulacean acid metabolism (CAM) Photosynthesis, which allows them to open their Stomata at night and store Carbon dioxide for use during the day. This unique Metabolism enables cacti to thrive in environments with intense Sunlight and limited Water availability. Cacti are also important components of Ecosystems, providing Habitat and Food for a range of Animals, from Insects to Mammals.
