According to the stems, this cell is 125 micrometers long and 50 micrometers wide.

Calculus 1

If 4 lengths of the organism reach this diameter, divide 500 by 4 to get an approximation of the cell size (125 micrometers in length).

Calculus 2

If 10 organism widths reach this diameter, divide 500 by 10 to get an approximation of cell size (50 micrometers wide).

With this information, we can conclude that according to the stems, this cell is 125 micrometers long and 50 micrometers wide.

We can estimate the size of the cell by using the following formula Size of the cell = FOV / Fit number. In this case, each cell is 125 μm length x 45.5 μm width.

How to measure a cell size?

Since cells are too small to be measured, we can make an estimation about their sizes by using a mathematical formula.

To do it, we need to know the objective size, the field of view, and the number of cells that fit in the field of view.

Size of the object = FOV / Fit number

  • Size of the object = size of the cell
  • FOV = Field of view = eyepiece (mm)/objective magnification              
  • Fit number = The number of times the object -cell- fits in the field of view

To answer this question, first, we will count the number of cells that fit the field. There are,

  • four cells across the horizontal field of view.
  • eleven cells across the vertical field of view.

Now, we will replace the terms in the given formula.

Length

  • FOV = 500 μm
  • Fit number = 4

Size of the cell = FOV / Fit number

Size of the cell = 500 μm / 4  = 125 μm

Width

  • FOV = 500 μm
  • Fit number = 11

Size of the cell = FOV / Fit number

Size of the cell = 500 μm / 11  = 45,45 μm

Hence, the approximate size of each cell is 125 μm length x 45.5 μm width.
