Cells Are Big

I didn't realize before what the scale of a cell is, but I was reading some from a bio textbook today. They say a typical eukaryotic cell would be 10-100 microns, so take 30 microns on a side. Then if a sugar molecule were as big as a person, the cell would be as big as Los Angeles (50km), except that it's 3D, so it's more like a thousand copies of Los Angeles stacked on top each other.
That allows for a hell of a lot of complexity. It gives some appreciation for just how grand the scale of life is. In particular, that of Haile Gebrselassie.
