A cactus is a type of plant that has sharp spines instead of leaves. It can usually be found in dry and hot regions where there is not much water. Cacti come in different shapes and sizes, and some even produce pretty flowers. You might see a cactus in a desert or in someone's home as a decoration. It's important to be careful around cacti because their spines can be painful if you touch them.
