Agave americana is a

✅ Explanation: Agave americana (century plant) is a classic example of a CAM (Crassulacean Acid Metabolism) plant.,CAM plants have evolved a specialized photosynthetic pathway to thrive in arid environments. They open their stomata at night to take in CO2, minimizing water loss, and store it as malic acid. During the day, stomata close, and the stored malic acid is converted back to CO2 for use in the Calvin cycle.

🔑Key Points :
-Crassulacean Acid Metabolism or CAM is a pathway for carbon fixation that is found in some plants.
-It is so-called because it was first found in the Crassulaceae family plants.
-It is a special adaptation for conserving water in xeric plants (that are found in dry conditions).
-In this process, the stomata open only at night and remain closed during the day.
-At night, the CO2 is converted into malic acid which is stored in the vacuole.
-During daytime as the atmospheric CO2 is absent, the malic acid is transported out of the vacuole and converted to pyruvate and CO2. This CO2 then takes part in the Calvin-Benson cycle in the chloroplast.
