I WONDER - How Small Are Cells?

Cells vary in size from one to 100 micrometers, similar to a single strand of hair. Unlike hair, cells are harder to see because they are like single dots, requiring a microscope for observation.

What is the range of lengths that cells can vary from?

How can the size of a cell be compared to a common object?

Why can we see strands of hair but not individual cells?

Explain why a cell is described as a 'single dot'.

What tool do we need to use to see most cells?
