State
A microscope magnifies objects too small for the naked eye to see, and cells are measured in micrometers because most fall below that threshold.
Show
A red blood cell spans about eight micrometers — small enough that roughly 250 could fit across a pinhead.
Watch for
Magnification enlarges an image; resolving power separates two close structures — a microscope needs both.
Builds on
- Nothing — this is a starting point.
