What does an Onion look like?

An onion typically has a round or bulbous shape with a thin, papery, outer skin that can be white, yellow, or red, depending on the variety. The inside consists of multiple layers of fleshy, juicy scales that are usually white or pale yellow. When cut, an onion releases a pungent aroma and can cause tearing due to its sulfur compounds. Overall, its appearance is distinct and recognizable, often used as a staple ingredient in many cuisines.
