Q. 1.Why is the lengths of the cells usually approximated when we record their values for length?
2. How several micrometers in a millimeter? How many millimetres in a micrometer?
3. A microscope has a field diameter of 2,000 microns under a total low power magnification of 100 X. This microscope has a 10X power ocular. Given this information, reply the following questions that appear below.
a. What is the power of the low power objective lens?
b. If a cell that is observed takes up approximately 1/6 of the field of view under low power, what is its approximate length?
c. If we now switch to high power using the 60 X objective lens, what is the magnification of this microscope?
d. Under the high power magnification you calculated in part (c.) above, what is the approximate length of our cell under high power?
e. About how much of the high power field diameter (fractional amount) does this cell occupy?
4. Indicate the approximate size of an individual cell in A in micrometers in the field of view below. Be able to give reason for the answer using written descriptions and calculations.
