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) Photosynthesis In this pathway, stomata open at night, which allows CO2 to diffuse into the leaf to be combined with PEP and form malate. This acid is then stored in large central vacuoles until daytime.

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.
