Cell size comparisons and Conversions
1) A typical human red blood cell has a diameter of about 7 micrometers
(µm), while a bacterial cell such as E. coli is about 2,000 nanometers
(nm) long. Which cell is larger, and by how much?
2) A plant cell is approximately 100 micrometers (µm) in diameter, and a
yeast cell is about 0.01 millimeters (mm) wide. Which cell is larger?
Show your calculations.
3)
An amoeba can be up to 0.5 millimeters (mm) long, while a paramecium
averages 250 micrometers (µm) in length. Which organism is bigger and
by how many micrometers?
4) A virus measures about 100 nanometers (nm) across, while a human
skin cell is around 30 micrometers (µm) in diameter. How many times
larger is the skin cell compared to the virus?
