The right answer is Pineapple.
Crassulacean acid metabolism (CAM) is a type of photosynthesis that allows certain chlorophyllous terrestrial plants to fix carbon. This crassulean chlorophyll assimilation metabolism concerns succulents.
This metabolism is generally found in plants living under arid conditions, such as cactus or pineapple. CAM plants represent about 10% of vascular plants.
