What part of the cactus does photosynthesis occur?
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.
How cactus leaves work?
Typically the leaves of the plant play the greatest role in photosynthesis. However, on cacti, the needles are actually modified leaves. These needles are a characteristic of protection and cannot carry out photosynthesis due to little surface area. Therefore, it is the stem that does the photosynthesis for the plant.
