Question: pineapples and cacti are examples of what type of plants?
Answer: Examples of CAM plants, besides the aforementioned cactus (family Cactaceae), are pineapple (family Bromeliaceae), agave (family Agavaceae), and even some species of Pelargonium (the geraniums). Many orchids are epiphytes and also CAM plants, as they rely on their aerial roots for water absorption.
