CAM plants, or Crassulacean Acid Metabolism plants, are a type of plant that have adapted to arid environments. They open their stomata at night to take in carbon dioxide, which helps reduce water loss during the hot daytime. This unique process allows them to thrive in conditions where water is scarce. These plants typically have thick, fleshy leaves that store water, making them well-suited for dry climates. Common examples of CAM plants include cacti, aloe vera, and pineapple. Their ability to conserve water while still performing photosynthesis is a key survival strategy in harsh environments.
