The bulb of an onion is formed from modified leaves. While photosynthesis takes place in the leaves of an onion containing chloroplast, the little glucose that is produced from this process is converted in to starch (starch granules) and stored in the bulb.
Chlorophyll and chloroplasts responsible for photosynthesis are therefore only present in the leafy part of the onion (above ground) and absent in the bulb (which grows below ground).
Unlike animal cells (such as cheek cells) the cell wall of an onion and other plants are made up of cellulose, which protects the cell and maintains its shape.
