Plants need water to survive, which is an idea we’re probably already familiar with. Cactuses are thrifty plants that live in dry regions. They may not get much moisture where they live, but they manage to make the most of what they do get.
Cactuses (sometimes also called ‘Cacti’) are types of plants called ‘Succulent,’ and are best known for living in hot, dry places like the desert, where they do not get a lot of water. Cactuses do need some water to survive, but can get along with a lot less than most plants.
One reason cactuses can get along with less water is because they don’t have leaves, so the water a cactus drinks does not evaporate as much as the water other plants drink. Additionally, cactuses have thick stalks which allow them to store water for a long time and roots that are good at finding and soaking up water even when it is scarce.
