The image is a close-up of an onion bulb. The bulb is in the center of the image and is facing towards the left side. It has a round, bulbous shape with a slightly wrinkled texture. The top of the bulb is slightly open, revealing the inner layers of the onion. The outer layer is a deep purple color and appears to be slightly darker than the inner layer. There are a few small roots visible at the bottom of the stem. The background is black, making the onion stand out.
