Verified step by step guidance1
Understand the different types of photosynthesis: C3, C4, and CAM. CAM (Crassulacean Acid Metabolism) is a type of photosynthesis adapted to arid conditions, where stomata open at night to minimize water loss.
Identify the characteristics of CAM plants: They typically open their stomata at night to take in CO2, which is then stored as an acid and used during the day for photosynthesis.
Recognize common examples of CAM plants: These often include succulents and plants like pineapple, which are adapted to dry environments.
Compare the given options: Maize, rice, and wheat are known to use C4 or C3 photosynthesis, which are not adapted to the same arid conditions as CAM plants.
Conclude that among the options provided, pineapple is the plant that uses CAM photosynthesis, making it the correct answer.
