Which type of cell is bigger, an onion cell or a cheek cell? How do you know?


I looked at both these cells under a microscope. The onion cell was clear but when I tried to look at the cheek sample, I couldn't see the cell properly which is why I'm asking this.When I tried to look up a picture of a cheek cell it was bigger then the onion cell. But according to 2 people I previously asked a onion cell is bigger. So, which one is it and how do you know?
