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 that’s exposed to direct sunlight. Cacti live in a desert environment where rain is rare, and even if it does rain, due to the heat water will simply evaporate. Most cactus stems have a pleated surface. This animal can survive in the tundra because of its layers of fur and fat.

So desert cacti have addressed this water loss by eliminating leaves altogether and moving the job of conducting photosynthesis to their thick stems, where the exposure to the atmosphere of tissues holding the water needed for photosynthesis is minimized. Then, after the soil dries out and they are no longer needed, the root hairs die away. This efficiency in transference is what allows cactus stems to become so large in diameter and thus store larger volumes of water. During the day, heat absorbed into the plant’s tissue brings the internal temperature up a bit, but the water’s thermal inertia keeps it from rising as high as the lethal external temperatures that can occur in the desert.
