Question

3. Size of Objects ind the size of a structure observed on the microscope use this formula: diameter of field size = diameter of the field Where n = the number of structures that can fit across the diameter of a of view. Answer the following: a. If you can see 5 equally sized organisms lined up next to each other on low power what would be the size of each organism (show work): b. If 42 red blood cells fit across the center of the high power field of view, what is the diameter of each RBC in micrometers (microns)? SHOW WORK

Explanation / Answer

a. if you can see 5 equally sized organisms lined up next to each other on low power, what would be the size of each organism?

field of view for low power (100X)= 1.1mm=1100micrometrer

size = (diameter of field/number of object)

=1100/5 micrometre

=220 micrometre

b.

You observed 42 RBC

Field of view diameter of a high power microscope (400X) = 300 micrometre

so the size of one RBC = 300/42 micrometre

= 7.143 micrometre
