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.
Onion cells are arranged in a closely packaged way. This is so that they layers of the onion can be thick and tough.

Onion skin is that filmy stuff between the layers of onions. It's just one cell thick, so it's idea for looking at through a microscope.
The tropical rainforest does not have thick waxy needles. The coniferous forest has thick waxy needles so that water on the needles wont easily be evaporated.
Succulent plants have thick, fleshy stems and/or leaves. In the Americas that includes the cacti.
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!
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.

The part of the onion you eat is underground. So no, onion has no chloroplasts in their cells.
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
