21. CAM Plant

          This is a picture of a pineapple. A pineapple is an example of a CAM plant. A CAM plant uses crassulacean acid metabolism (CAM), which is a type of photosynthesis that is adapted for dry climates and allows the plant to conserve water. Pineapples use CAM photosynthesis in order to lessen the effects of photorespiration. Because pineapples are CAM plants, they are able to survive long periods of drought. Pineapples are also able to grow in hot climates because using crassulacean acid metabolism means they do not lose a lot of water during the day.
