Cacti have reduced their leaves to spines to reduce water loss and to protect the cactus. Cactus tubercles and ribs play an important role in water storage and retention, as they allow the stem to expand to increase the volume of moisture it can hold without stretching or bruising and then retract as the stem loses water, which minimizes the amount of surface area thats exposed to direct sunlight. I hope you have enjoyed this look into the amazing cactus adaptations that help these plants survive in desert environments.
