cactus
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.
cactus have a hollow stem. it is where they store water and food for survival
The 'spines' of a cactus attach directly to the stem of the plant.
The chlorophyll in the cactus's green stem and branches is responsible for photosynthesis, which is the process of creating food for the plant through the absorption of light energy. The food produced is stored in the form of sugars and starches, providing energy for growth and survival.
Cactus are desert plants.Their leaves have turned into thrones.
A cactus has no leaves but does have a stem.
Cactus
it stores water in its large stem
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
