Question

What is the actual size of a red blood cell

Answer 1

Actual size, 6 to 8 micrometers in diameter. You could line them up across a large pizza, with 67 thousand of them lined up side by side across the pizza. I didn't figure how many to the moon.

Answer 2

Thanks, could it be magnified 500x with a Microscope? Or could it only be magnified 400x with a compound light microscope?

Answer 3

with a power of 200, you can distinguish the cells in a blood smear. Typically, one starts looking at a power of 250, then shifts to 400 power once the right cell is in the center of vision.
