Question
Blood cells can be identified by their round appearance. Unlike plant cells, they do not have cell walls. At 40x, how many individual blood cells can be seen in the viewing field
Solution
The number of individual blood cells that can be seen in the viewing field at 40x magnification would depend on the size of the viewing field of the microscope being used, as well as the size of the blood cells themselves.
Here's a step-by-step guide on how you might estimate this:
-
Determine the diameter of the field of view for your microscope at 40x magnification. This can often be found in the microscope's manual or manufacturer's specifications. If not, you can calculate it by viewing a ruler or micrometer under the microscope.
-
Determine the average diameter of a human blood cell. This is typically around 6-8 micrometers.
-
Calculate the area of the field of view using the formula for the area of a circle (Area = π*(d/2)^2), where d is the diameter of the field of view.
-
Calculate the area of a blood cell using the same formula.
-
Divide the area of the field of view by the area of a blood cell. This will give you an estimate of how many blood cells can fit in the field of view.
Remember, this is just an estimate. The actual number could be less due to the fact that cells are three-dimensional and may overlap in the field of view.

At 100x, you will see a cell that is larger and has a dark shape in it. This cell doesn’t look like the others because it is a white blood cell and it functions to protect your body against microbes. Red blood cells do not have a nucleus. White blood cell count is used as a diagnostic tool to determine if someone is sick. If you were fighting an infection, would you expect to have more or less WBC’s? Why?

25. A particular compound microscope, with the 43x objective in position, has a diameter of thefield of view of approximately 0.31 mm and an area of approximately 0.1 mm2. The diameter of thefield of view is inversely proportional to the magnification of the objective. Counting left to rightone observes 15 rectangular onion epidermal cells across the field of view with the 43x objective inplace. Counting from top to bottom it can be observed that four cells span the diameter of the field.Using the 43x objective, one sees an average of 12 stomates per field of view. What is the bestestimate of the density of stomates per sq mm of epidermal surface?A. 12B. 15C. 36D. 120E. 150
