6 µm

Long axis of the egg-shaped cell

A single cell of the yeast that raises bread and brews beer. About 6 µm long.

How big is that?

6 µm is 78% of a red blood cell.

Yeast cell is the 4th smallest of the 32 Tiny Worlds objects, and the 4th smallest of the 172 objects across all five SizeItUp games.
