Microscope Functions
Duration: 00:00:21
Advance mode: Auto
A microscope can be used to see objects at
different magnifications. The higher the
magnification the closer the detail of the object.
To calculate the power of magnification, multiply
the power of the eyepiece by the power of the
objective.
Eyepiece

Notes:
A microscope can be used to see objects at
different magnifications. The higher the
magnification the closer the detail of the object.
To calculate the power of magnification, multiply
the power of the eyepiece lens by the power of
the objective.

As you increase the magnification of an object
you can see better details of the object, but you
cannot see as much of the object because you are
closer to it.
This is a table to show sample magnifications on a
standard light microscope.

Cells come in all shapes and sizes. Below
you can see a muscle cell, a nerve cell and
red blood cells. Not all cells have the exact
same components or make up.

1-No nucleus, and their genetic
material is stored on DNA called plasmids.
2-No membrane-bound organelles
3-Have ribosomes (like eukaryotes)
4-Smaller than eukaryotes
5-Bacteria are all prokaryotes
6-Much more simple than eukaryotes

Traits of Eukaryotes
Notes:
1-Genetic material
(DNA) is stored in a
nucleus.
2-Have membranebound organelles
(mitochondria, vacuole,
chloroplasts)
3-Have ribosomes
4-Larger and more complex than prokaryotes
5-All plants, animals, fungi and protists are
composed of eukaryotic cells.
