An onion is a bulb, which is basically a living plant (which is why if you convince it that it's spring it will sprout again). So cooking it you kill the plant itself.
You usually see concentric circles. The inside of an onion is arranged in layers - like a ball inside another ball.

Onion cells do not have chloroplasts because the onion is underground where there is no light. Without light chloroplasts have no purpose, so onion cells just don't have them.
Heat an onion on a frying pan OS a saucepan or something similar and after a few minutes drops of onion oil will start accumulating. Heat an onion on a frying pan OS a saucepan or something similar and after a few minutes drops of onion oil will start accumulating.

You can tell if an onion cell is alive by observing its turgidity and color. Live onion cells are turgid, meaning they are firm and full of water, giving them a healthy green color. Dead onion cells will appear shriveled, discolored, and lack turgidity. You can also perform a simple plasmolysis test to determine cell viability.
The liquid inside an onion cell, at the center, is the same as in all other cells and is called cytoplasm.
