    Question: Which one of the following is an example of a CAM (Crassulacean Acid Metabolism) plant?

    Options:

    Maize
    Pineapple
    Apple
    Mango

    ✅Explanation:
    -1) CAM (Crassulacean Acid Metabolism) is a photosynthetic pathway found in certain plants that allows them to adapt to arid or water-limited environments.
    -2) Pineapple is an example of a CAM plant. It is well-known for its ability to survive in dry and tropical climates.
    -3) CAM plants, including pineapple, have a unique carbon fixation mechanism. They open their stomata at night to minimize water loss through transpiration and absorb carbon dioxide, which is converted into organic acids.
    -4) During the day, the stomata remain closed to reduce water loss while photosynthesis continues using the stored organic acids.
    -5) Other examples of CAM plants include succulents, such as cacti and jade plants, as well as certain orchids and bromeliads.
    -Maize (corn), apple, and mango are not examples of CAM plants. They utilize the C3 photosynthetic pathway, which is the most common pathway among plants.
