Problem 1:


LPO: 2mm (diameter); # of cells: 5 cells; What is the size of each cell (in LPO) in microns?

Problem 2:


LPO: 2 mm (diameter); # of cells: 2 cells; What is the size of each cell (in HPO) in microns?

Problem 3:

Assumption: Assume you have relatively three equal sizes of cells

If this group of bacteria composed of three longitudinal cells was viewed under a high powered objective with a field of view of 0.1 mm, the length of one cell would be? (in microns)

Problem 4:

You are using a microscope with the LPO (magnification 500X) diameter measured as 2.8 mm. If the organism X occupies only half of the field of view under the HPO (magnification 800X), what is the length of organism X? (in microns)
