Because it has no true leaves, the only part of a typical cactus that can produce food via photosynthesis is the stem. Through evolution, the leaves have become modified and not form the spines of the cactus, loosing their ability to photosynthesise
cactus have a hollow stem. it is where they store water and food for survival
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
A cactus makes food through the process of photosynthesis, like any other plant. The difference between a cactus making food from another plant is that cactus have their leaves reduced to spines, therefore, their stem contains chlorophyll and photosynthesis takes place through the stem.

Leafless cactus plants
A cactus stores its food and water in its stem. The stem is thick and fleshy, allowing it to hold onto water for long periods of time. Additionally, cacti have specialized tissues and cells that can store water efficiently for use during dry periods.
It's the thorns on cactus plants and roses that make them both difficult to hold. On both plants, the thorns serve to defend and protect the stem and the flower. But on the cactus, the thorn is a modified leaf. On a rose, the stem has both thorns and regular leaves.
A cactus is an autotroph. This is because autotrophs make their own food using photosynthesis. A cactus uses photosynthesis to make its own food.
The 'spines' of a cactus attach directly to the stem of the plant.
A cactus stores water in its stem.
Water is stored in tissue in the stem of the cactus.
The cactus gets its food by taking in water and dissolved nutrients through the roots. The nutrients and water flow up through the stem. With the help of sunlight, the photosynthetic process takes place of changing water and nutrients into such energizers as sugars and carbohydrates. The energy sources then are sent throughout the plant to help in such basic processes as growing and flowering.
