| A | B |
|---|
| Who was the first to discover and name "cells"? | Robert Hooke (in 1665) |
| What type of cells were the first cells to be seen under a microscope? | Cork cells (by Robert Hooke in 1665) |
| What was Anton van Leeuwnhoek's contribution to the cell theory? | He was the first person to see living cells under a microscope. He looked at pond water in 1675 and saw a bunch of single cell organisms swimming around. He called them "animalcules." |
| Who coined the phrase "All plants are made of cells," in 1838? | Schleiden |
| Who coined the phrase "All animals are made of cells," in 1839? | Schwann |
| Who was the first to state that "All cells come from pre-existing cells." in 1858? | Virchow |
| What is the first statement of the modern cell theory? | All living things are made of cells. |
| What is the second statement of the modern cell theory? | Cells are the basic units of structure and function in all living things. |
| What is the third statement of the modern cell theory? | All cells come from pre-existing cells. |
| What do all cells have in common? | A cell membrane, DNA, cytosol, and ribosomes (Red blood cells lose their DNA and ribosomes as they mature) |
| All cells can be divided into these two categories based on whether they have a nucleus or not. | Prokaryotic (no nuclues, includes all types of bacteria) and Eukaryotic (all other types of life except the two kingdoms of bacteria) |
Which type of electron microscope produces 2 dimensional images like the one below?,  | transmission electron microscope (TEM) |
Which type of electron microscope produces three dimensional images like the one below?,  | scanning electron microscope |
Which type of microscope can produce an image of something as small as the molecules of DNA below?,  | Scanning probe microscope |
What type of microscope is pictured below?,  | Compound Light Microscope |
What are the names of each of the parts of the light microscope pictured below?,  | ., |
| What do you call the lens on a microscope that is closest to the eye? | ocular, |
| What do you call the structure on a microscope that adjusts the amount of light on the image and where is it located? | Diaphragm and it is always located underneath the stage., |
| What is the difference between magnification and resolution? | Magnification is how many times bigger the image in a microscope appears while resolution is how detailed you can see things. High magnification without good resolution is worthless. |
| How do you calculate the total magnification of a compound light microscope? | Total magnification = magnification of the objective lens X the magnification of the ocular |
| What should you never touch once you have the image in focus at low power and you've switched to a higher power? | the coarse adjustment |
| What do you call the lenses on a light microscope that are located closest to the slide ? | the objective lenses, |
| For a light microscope, what power should you be on when you are trying to get the image in focus and which adjustment knob should you use to focus? | You should be on the lowest power using the coarse adjustment knob to bring the image into focus., |
| How should you hold a microscope when you are transporting it from one place to another? | Two hands, one on the base and one on the arm of the microscope. |
| Cells with a nucleus are called __. | Eukaryotic cells, 
|
| Cells without a nucleus are called ___. | Prokaryotic cells,
|
| Who stated that many organelles may have at one time been free-living bacteria? | Lynn Margulis in 1970 (she found evidence that bacteria may have formed symbiotic relationships inside larger cells and eventually became inseparable) |
