Have you ever heard someone say, “All cacti are succulents, but not all succulents are cacti?”
Have you ever wondered what the difference is?
Well, in the most basic sense, cacti are succulents that do not have leaves. However, the mere presence of spines (the prickly part of cacti) is not the sole indicator that a plant is a cactus. The various families are actually determined by flower form (just like the orchid).
