Detailed explanation-1: -Crassulacean acid metabolism (CAM) is a specialized pathway that stores photosynthetic products at night, allowing stomata to remain closed during the day. From: Climate Change Biology (Third Edition), 2022.

Detailed explanation-2: -Ans: When growing in arid conditions, plants such as cacti and pineapples use the crassulacean acid metabolism (CAM) pathway to reduce photorespiration and conserve water. The name derives from the Crassulaceae family of plants, which is the group of plants in which scientists found the pathway for the first time.

Detailed explanation-3: -Crassulacean acid metabolism (CAM) is a photosynthetic adaptation to periodic water supply, occurring in plants in arid regions (e.g., cacti) or in tropical epiphytes (e.g., orchids and bromeliads).

Detailed explanation-4: -Crassulacean acid metabolism (CAM) CAM is a mechanism of photosynthesis involving double fixation of CO2, which occurs in succulents belonging to Crassulaceae, cacti, euphorbias and some other plants of dry habitats where the stomata remain closed during the daytime and open at night.

Detailed explanation-5: -Crassulacean acid metabolism (CAM) is a major physiological syndrome that has evolved independently in numerous land plant lineages. CAM plants are of great ecological significance, and there is increasing interest for their water-use efficiency and drought resistance.
