Photosynthesis takes place in the stem of the cactus. Needles are the cactus' equivalent of leaves. But they don't have enough surface area to support photosynthesis or to store photosynthetic byproducts. So the cactus' stem is bigger, taller, and wider than in many other plants. The cactus needs all that extra space to move around and store water, dissolved nutrients, and byproducts of the photosynthetic interaction with sunlight.
In a cactus the leaves have been reduced to spines, to reduce the surface area from which water can be lost and to deter animals from eating the plant. As there are no leaves, photosynthesis must take place in the stem.
The flattened stems of a cactus, also known as the pads or cladodes, are adapted for photosynthesis. These pads have a large surface area that allows for increased sun exposure, while the waxy coating helps reduce water loss. Additionally, the presence of specialized cells called chloroplasts within the pads enables photosynthesis to occur efficiently in these plants.

That is the dark reaction. It needs no light
Photosynthesis in a cactus primarily takes place in its green stem or pads. These parts contain chlorophyll, the pigment responsible for photosynthesis, and allow the cactus to convert sunlight into energy. The cactus has adapted to reduce water loss by performing photosynthesis primarily during the cooler night hours.

A cactus is an autotroph. This is because autotrophs make their own food using photosynthesis. A cactus uses photosynthesis to make its own food.
Cactus, like other plants, uses photosynthesis to get energy.
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
