The Edible Onion is naturally a biennial plant, so it takes two years to reach maturity and flower. This means it needs to store food over the winter period, It does this by thickening the bases of its leaves to form a bulb during the first year of growth. The bulb stores sugars and starches for the next growing season and we harvest the onion at this stage to make use of this food store.

Why is the Bulb of the onion plant so big?
It is big because before leaves sprout, the bulb is the source of food because without leaves, there is no photosynthesis thus no food unless the bulb feeds the plant (which as I said before, it does). The bulb of the onion also stores energy. Hope this satisfies!
Why do the leaf cells of the onion scale contain no chloroplasts?
Because an onion develops in the ground, and chloroplasts develop in the sunlight. Therefore no chloroplasts form. Think of it this way: Tree leaves contain chloroplasts because they contain chlorophyll in order for the leaves to turn colors. But who has ever heard of an onion changing colors because it's fall?! Onions dont need chloroplasts, so they dont have them.

Onions themselves are root bulbs, and so cannot photosynthesize. Keeping that in mind, onion leaves and the sprouting plant from the onion bulb CAN photosynthesize like all other leaved plants. Hope this helps! Daniel A
