Holds and protects the genetic information of the cell.
WHere proteins are made
Controls what enters and leaves the cell
cell membrane (9)
Provides added structure and support to plant cells. Found outside the cell membrane.
cell wall (8)
Pathway for proteins
endoplasmic reticulum (5)
Modifies, sorts, packages and ships out proteins to where they are needed.
Contains digestive enzymes to break down old cell parts/waste.
Site of photosynthesis. Uses the suns energy to make food energy (glucose).
Site of cellular respiration. Uses food energy (glucose) to make usable energy (ATP)
Storage area for water and nutrients
Framework of filaments and fibers that supports the cell structure.
Long whip-like tail tht helps with movement.
Many small hairs that helps with movement.
Helps with cell division

What is the only example of a prokaryote?
Microscope that uses light and two separate lenses to magnify a very thing image. Can magnify up to 2000x (our only go up to 400x).
Compound light microscope
Microscope that uses light and binocular lenses (2 eyepieces) to magnify a larger object. Can magnify up to 50x
Stereomicroscope (dissecting microscope)
Image in inverted (upside down and backwards) when using this microscope
Compound light microscope.
How is total magnification determined?
ocular lens x objective lens
If the ocular lens is 10x and the objective lens is on 4x, what is the total magnification?
Area seen when looking through the microscope
Field of view
What happens to the field of view as you switch to a higher power?
On which power is you image smallest but field of view largest?
Microscope that uses electrons to show the surface of an object (magnifies up to 100,000x)
Scanning electron microscope
Microscope that shoots electrons through a thin object so you can see the inside (magnifies up to 200,000x)
Transmission electron microscope
What si a problem with using the electron microscope?
Specimen must be dead.
Larger knob on the side of the microscope that can only be used with scanning and low powers.
Coarse adjustment knob
Smaller knob on the side of the microscope that is used mostly on high power.
Fine adjustment knob.
Controls the amount of light shining on an object.
Eyepiece (10x) lens you look through.
Where the objective lenses are attached. Rotates to change objective lenses.
Where your bottom hand should be when carrying a microscope.
The part your other hand should hold while carrying a microscope (not the base)
3-4 lenses with different magnifications that can be changed to see more or less of your specimen.
Where the specimen/slide is places for viewing.
Put the following organisms in order from more primitive to more recent: aerobic prokaryotes, anaerobic prokaryotes, eukaryotes
