HeLa Cell（20 µm）与a cloud droplet（20 µm）和a human hair（70 µm）按真实比例并排绘制 — 按比例绘制，从左到右依次是：HeLa Cell (20 µm)、Cloud droplet (20 µm)和Human hair (70 µm)。

比较

它实际有多大？

About the same width as a cloud droplet
As wide as about 3 red blood cells side by side
About 3 would fit across a human hair
About 5 would fit across a human egg cell
About 10× the length of an E. coli bacterium
