BIO 1500 LAB- MICROSCOPY AND PROTISTS | THE SMART
WAY TO PASS | REAL TESTS, REAL RESULTS!
Types of microscopes - Answer: 1. dissecting- looks at overall structure of an organism
2. compound- for organisms organelles, cells, etc.
3. inverted- looks at bacterium
Know the parts of the microscope - Answer:
At 100x we must always - Answer: use oil immersion
Total magnification= - Answer: ocular lens (10x) x objective lens
microscope image always appears - Answer: upside down and reversed (inverted)
How do you move the specimen on the microscope? - Answer: ALWAYS move the slide in
the opposite direction to what you see
proper care and use of microscopes: right/wrong - Answer: Right
1. always carry microscope using 2 hands (one under base and one on the arm)
2. always start at lowest magnification, focus on object, then increase
3. use coarse focus knob ONLY with lowest scanning objective
4. store scope with cord wrapped around hanger/base, with scanning objective in place
and stage fully lowered
Wrong
1. DO NOT use oil immersion lens without oil

, 2. DO NOT use anything other than lens paper to clean lens
locomotion - Answer: movement (flagella, cilia, pseudopodia)
supergroup is the same thing as - Answer: clade
protists are NOT - Answer: monophyletic (do not share a common ancestor)
Protists are - Answer: Eukaryotes
- they can be unicellular, multicellular, or colonial
- they can also be autotrophic, heterotrophic, mixotrophic, parasitic
- either sexually or asexually reproduce
unicellular - Answer: A single celled organism
colonial - Answer: individual organisms of same species living closely together.
If separated, they CAN survive
multicellular - Answer: multiple cells
if separated, CAN NOT survive
Protists are classified as... - Answer: 1. plant-like
2. fungus-like
4. animal-like
