Which of the following choices correctly matches a tool and its proper application?

a. cell fractionation to study the function of specific organelles transmission

b. electron microscopy (TEM) to study the surfaces of preserved cells scanning

c. electron microscopy (SEM) to study the detailed movements of living cells transmission

d. electron microscopy (TEM) to study the movement of organelles within a living cell light microscopy to study the internal structure of cilia

a. cell fractionation to study the function of specific organelles transmission

Explanation:

Cellular fractionation is a technique of isolation / purification of different parts of cells, such as cellular organelles, in order to be able to analyze them by physical and chemical methods. That is, we can say that cellular fractionation is made to study the function of specific organelles transmission.

Cellular fractionation represents an alternative and / or complementary form to microscopy to further study the functioning of subcellular organelles.
