I'm trying to find out the difference between a cactus and a succulent.

A succulent is a plant that has adapted to dry conditions by storing water in its leaves, stems, or other tissues. Cacti are also succulents, but they have adapted to arid environments by having thick, fleshy stems and shallow roots. The most obvious difference between them is their appearance - cacti look spiky and prickly, while succulents tend to be more rounded and cushion-shaped.
