Why do onion cells lack chlorophyll?
The insides of the cells squished up and the chloroplasts all bunched together because the water in the cytoplasm was “sucked out” of the cell by a phenomenon called “osmosis.” Since the onion bulb grows underground, it doesn’t see any sunlight and so it doesn’t have any chloroplasts for photosynthesis.
