​Parts of the cell theory

​1. All organisms are made of cells (plants, animals, fungus...)

​2. All cells come from preexisting cells.

​3. Cells are the basic structure of life.

​People to know...

​The microscope

​Looking at cells and discovering the three parts of the cell theory wouldn't have been possible without the microscope. Cells are too small to see without a microscope.

Multiple Choice

You must carry a microscope with...

• your nose in the air like you just don't care

• your hand and your chin

• two hands, one under the base and one on the top

Multiple Choice

To focus a specimen, it is best to start with which objective:

• high power

• low power

• scanning

• ocular

Multiple Choice

When moving to the next higher power objective,

Focus using only the_________ adjustment knob; the object quickly comes into focus with very light adjustment

• coarse

• fishy

• fine

• crunchy

Multiple Choice

If you move the slide left while viewing, in which direction will it appear to move?

• right 
• left
• up 
• down

Multiple Choice

Electron microscopes use a beam of _________________ to produce an image magnified up to 100,000 or more

• Sunlight
• Lasers
• Electrons

A scanning electron microscope (SEM) is a type of electron microscope that produces images of a sample by scanning the surface with a focused beam of electrons

The transmission electron microscope is used to view thin specimens (tissue sections, molecules, etc) through which electrons can pass generating a projection image.

Multiple Choice

Type of microscope that commonly uses visible light and a system of lenses to magnify images of small objects

• Electron Microscope

• Scanning Electron Microscope

• Transmission Electron Microscope

• Light Microscope

A dissecting microscope is used to view three-dimensional objects and larger specimens, with a maximum magnification of 100x
