Is it true that the stem of the cactus plant prepares food without leaves?

A cactus plant prepares its food through photosynthesis, but unlike most other plants, it does not rely on its leaves for this process. Instead, the stem of a cactus is modified to synthesize food, which makes it green in color due to the presence of chlorophyll. The stem is also bulbous and succulent, serving to store food material and water. In contrast, the leaves of a cactus are modified into spines, which serve to reduce the surface area for transpiration and protect the plant from predators. Therefore, it is true that the stem of a cactus plant prepares food without leaves.
