Question

Most compound light microscopes have a field of vision at a low power of about 1.4 min. If you are looking at a eukaryotic cell that has a diameter close to 60% of the field of vision at low power, what would be the diameter of the cell in micrometers (um)

a. 840 um
b. this cannot be determined with the given information
c. 84000 um
d. 0.84 um​

Answer 1

The diameter of the eukaryotic cell is 840 micrometers (µm), calculated by taking 60% of the microscope's low power field of vision, which is 1400 micrometers, based on standard microscope specifications.

Step-by-step explanation:

The student's question involves determining the size of a eukaryotic cell based on its proportion relative to the field of vision at low power using a compound microscope. Given that most compound light microscopes have a field of vision of about 1.4 millimeters (1400 micrometers) at low power, and a eukaryotic cell is about 60% of this field, we can calculate the diameter of the cell as follows:

• Convert the field of vision from millimeters to micrometers if necessary (1 mm = 1000 µm).
• Multiply 1400 µm by 60% (or 0.6) to get the diameter of the cell in micrometers.
• The calculation would be 1400 µm x 0.6 = 840 µm.

Therefore, the diameter of the eukaryotic cell would be 840 micrometers (µm).
