With an electron microscope you can also observe…?
Viruses
What are the two types of electron microscopes?
Scanning and transmission
A scanning electron microscope reflects a beam of…?
Electrons off the exterior of the specimen which produces a 3-D view of specimens surface
A transmission electron microscope transmits the beam of…?
Electrons through an extremely thin section of the specimen which is used to study the structure of organelles within a cell
All the single celled protozoa are placed in their own kingdom called
Protista
Amoeba are constantly changing their shape and move by extensions of their cytoplasm called..?
Pseudopodia
And electron microscope uses a beam of..?
Electrons rather than a beam of light to observe and specimens
Which is more important in the quality of a microscope lens, it’s magnification arts resolving power? Why?
Resolving, because it gives you the ability to see fine details between two objects to see them as separate

- cells that possess this faculty are generally referred to as amoebas
Eukaryote
A cell having DNA inside a distinct membrane enclosed nucleus
Prokaryote
A cell whose genetic material is not in clothes in a nuclear envelope
Vibrio cholera is a vibrantly motile bacterium, what type of microscope would be most useful in observing the motility for this microbe?
Dark field microscope
What type of microscope would be most helpful in studying the 3-D fine structure of the surface of my micro villi from the intestine?
Scanning electron microscope
