How big is a cheek cell
They're everywhere. Literally. There are some 2.5 million ants to a single human being. Which is a lot. You can see them, but they are small. In fact, they are generally around 3mm in length. Which is quite small, right?
But what if we went smaller?
A human hair.
Size of cheek cell in mmSmall enough? Well, the average human hair can be as small as 100 micrometres (µm). This is now smaller than an ant, which you can see running up your arms easily, compared to the hairs on it.
Smaller still? OK.
A palisade leaf cell.

You want more? Fine.
