Schleiden, Schwann, & Virchow
Invented the compound microscope
Came up with the Cell Theory
![Page 9: Discovering Cells WITH MICROSCOPES. What are Cells?](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649e745503460f94b74daa/html5/thumbnails/9.jpg)
What is the Cell Theory?
All living things are made up of cells
Cells are the basic units of structure and function of all living things
All cells are made from other cells

MICROSCOPES
What is a microscope?
How do microscopes make objects look larger?
Instrument that makes small objects look larger

MICROSCOPES
What is a microscope?
How do microscopes make objects look larger?
Instrument that makes small objects look larger
Uses lenses to magnify the object

TYPES OF MICROSCOPES
SIMPLE
One lens

TYPES OF MICROSCOPES
COMPOUND
TWO lenses
![Page 16: Discovering Cells WITH MICROSCOPES. What are Cells?](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649e745503460f94b74daa/html5/thumbnails/16.jpg)
TYPES OF MICROSCOPES
LIGHT: Magnification=
makes object bigger
Resolution= makes object clearer
ELECTRON: Uses electrons to
magnify objects
![Page 17: Discovering Cells WITH MICROSCOPES. What are Cells?](https://reader036.fdocuments.us/reader036/viewer/2022062314/56649e745503460f94b74daa/html5/thumbnails/17.jpg)
CALCULATINGMAGNIFICATION
TOTAL MAGNIFICATION= ocular power x objective lens power
Ocular power is generally 10X, meaning it has a magnification or power of 10X
Objective power depends on which lens you are using= 4X, 10X, or 40X
