No, onion cells do not have photosynthesis.
Onion cells lack chlorophyll, the pigment necessary for photosynthesis. This is because onions grow underground, away from sunlight, which is essential for the photosynthetic process. Their primary function is to store energy, typically in the form of starch or sugars, rather than to produce it through photosynthesis. Since photosynthesis is the process of converting light energy into chemical energy, its absence means the cells remain colorless, which further supports their non-photosynthetic role.
In summary, the absence of chlorophyll and their underground growth prevent onion cells from carrying out photosynthesis.
