1. light microscope visible light is passed through a specimen and then through glass
lenses
2. Magnification the ratio of an object's image to its real size
3. Resolution the measure of the clarity of the image, or the minimum distance of two
distin-
guishable points
4. Contrast visible differences in brightness between parts of the sample, low contrast
is less bc more darkness
5. Organelles the membrane-enclosed structures in eukaryotic cells
6. Electron two basic types of EM are used to study subcellular structures
micro-
scopes (EM)
focus a beam of electrons onto the surface of a specimen, providing images
7. Scanning that look 3-D
elec- tron
microscope
(SEM) focus a beam of electrons through a specimen
8. Transmissi
on electron
microscope
(TEM)
9. Cell fractionation takes cells apart and separates the major organelles from one another to
study
them on their own
10. Basic features -Plasma membrane
of all cells -semifluid substance called cytosol

13. Nucleoid DNA in an unbound region
14. Cytoplasm bound by the plasma membrane
15. Prokaryotic cell
16. Eukaryotic cells DNA in a nucleus bounded by a double membrane
membrane-bound organelles
cytoplasm
17. Plasma a selective barrier that allows suflcient passage of oxygen, nutrients,
mem- brane and waste to service the volume of every cell; lets certain things in and
out
18. Plasma
mem- brane
