O2 Intro to Cells and Microscopy

Front

What is the field of view in microscopy?

Back

The field of view is the visible area that can be seen through the microscope at a given magnification.

Front

How do you calculate the size of an object using the field of view?

Back

Size of object = Field of view ÷ Number of objects that fit across the field of view.

Front

What is magnification in microscopy?

Back

Magnification is the process of enlarging the appearance of an object through a microscope.

Front

What is the formula for calculating magnification?

Back

Magnification = Image size ÷ Actual size.

Front

What does resolution refer to in microscopy?

Back

Resolution refers to the clarity of an image, or the ability to distinguish two close objects as separate.

Front

Why are viruses considered non-living organisms?

Back

Viruses cannot reproduce without a host, do not metabolize food into energy, and do not have organized cells.

Front

What is the typical size range of bacteria?

Back

Bacteria typically range from 0.5 to 5.0 micrometers in size.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and organelles.

Front

What is the purpose of using different objective lenses in microscopy?

Back

Different objective lenses provide varying levels of magnification and resolution for observing specimens.

Front

What is the significance of the 10x and 100x objectives in microscopy?

Back

The 10x objective provides low magnification for initial observations, while the 100x objective provides high magnification for detailed examination.
