Is there a difference between a cactus and a succulent?
assistant
Yes, a cactus is a type of plant that has spines or are armed with thorns. A succulent is a type of plant that stores water in its leaves, stems, and other tissues for later use. Cacti have adapted to dry environments by having thick, waxy skin and shallow roots to absorb moisture from the air. Succulents store water in their cells, allowing them to survive longer periods without rain.
