Chapter 4, Problem 2TYK
Summary Introduction
Introduction: Cell is the smallest fundamental unit of structure and function in all living organism. It is quite difficult to observe the ultra-structure of cell with naked eye. Inside the cell, cell-organelles are present; those are very minute to identify by electron microscope. So, high magnified electron microscope is needed for the observation of ultrastructure of cell and the cellular organelles.

Many microscopy techniques use cell characteristics, such as differences in absorption, refraction, or even light polarization. Fluorescence microscopy provides an image from a single molecular species, simply by looking at the fluorescence emission. How does fluorescence microscopy compare to other techniques?
A.Image the location, diffusion or even transport of intracellular molecules.B.Accurately calculate the cytosol refractive index of a cellC.Count the number of cellsD.Accurately measure kernel size
After investigation of a specimen under light microscope and electron microscope, numerous amounts of spherical shaped particles were seen in the electron microscope while this type of structure was not visible under the light microscope. Further characterization revealed that these particles lack cellular organelles (like the nucleus, mitochondria…). Considering the above circumstance, answer the following questions.
(A) What do you think would be the size of the specimen?
(B) What do you suspect these particles are most likely to be?
(C) Would you define these particles as living? Why/why not-justify your answer briefly
