Question

observation of a frog blood cell slide
a. under highest power, focus on the prepared frog blood cell.
b. observe and draw what you see below, draw about 4 - 5 cells.
c. estimate the length of a single cell by determining how much of the field they cover. what is the approximate size of the cell in microns? show all calculations.

Explanation:

Step1: Assume field - of - view diameter

Let's assume the diameter of the field - of - view (FOV) at the highest power of the microscope is known. For example, if the diameter of the FOV at high power is $d = 0.5$ mm or $500$ microns.

Step2: Estimate cell coverage

Count how many cells can fit across the diameter of the FOV. Suppose we estimate that 10 cells can fit across the diameter of the FOV.

Step3: Calculate cell length

The length of a single cell $l$ can be calculated by dividing the diameter of the FOV by the number of cells that fit across it. So $l=\frac{d}{n}$, where $d$ is the diameter of the FOV and $n$ is the number of cells across the FOV. Substituting $d = 500$ microns and $n = 10$, we get $l=\frac{500}{10}=50$ microns.

Answer:

The approximate size of the cell is 50 microns (assuming a FOV diameter of 500 microns and 10 cells fitting across it). The actual value may vary depending on the real - world diameter of the FOV and the number of cells across it.
