Key Differences
Cactus refers specifically to members of the Cactaceae family, characterized by their spiny stems, absence of leaves, and ability to store water in their thickened stems. Succulent is a broader term that encompasses a variety of plants from different families, all of which have developed the ability to store water in their leaves, stems, or roots.
While all cacti are succulents due to their water-storing capabilities, not all succulents are cacti. Succulents can have diverse forms and structures, some having thick leaves or rosettes, whereas cacti are typically recognized by their spiny, leafless appearance.
Cacti often have areoles, which are small, cushion-like structures from which spines, flowers, and branches grow. Succulents, on the other hand, do not have areoles but may have other distinguishing features such as fleshy leaves or unique growth patterns.
