a. iris diaphragm.
b. oculars.
c. body tube.
d. stage clips. a. iris diaphragm.
T/F: You should always begin looking at a slide with the lowest power objective in place.
True
The 4X objective is also called the ______ objective.
a. scanning
b. low-power
c. high-powered.
oil immersion a) Scanning
,Another name for the 10X objective low power
Another name for the 40X objective high power
The 100X objective is also called the ______ objective. Oil Immersion
What are the three domains? Bacteria, Archaea, Eukarya
Bacteria - Domain of unicellular prokaryotes that have cell walls containing
peptidoglycan
- (microbiology) single-celled or noncellular spherical or spiral or rod-shaped organisms lacking
chlorophyll that reproduce by fission
Archea Domain of unicellular prokaryotes that have cell walls that do not contain
peptidoglycan
Eukarya Domain domain consisting of all organisms that have a nucleus; includes protists,
plants, fungi, and animals
,Prokaryotes vs. Eukaryotes PROKARYOTES ("pro" = before, "karyon" = nucleus)
1. Unicellular: Bacteria and blue-green algae
2. No nucleus; nucleiod region with single
circular DNA; single chromosome;
3. Smaller
4. Cell wall in all
5. Ribosomes (30 & 50S)
6. No membrane-bound organelles
7. Transcription and Translation in cystosol
EUKARYOTES ("eu" = true, "karyon" = nucleus)
1. Unicellular or Multicellular: protists, fungi,
plants & animals
2. Nucleus; consist of mutiple chromosomes
3. Bigger
4. Cell wall ONLY in fungi & plants
5. Ribosomes (40 & 60S)
, 6. Membrane-bound organelles
7. Transcription in nucleus; Translation in cytosol
BOTH
1. Cytoplasm
2. DNA
3. Cell membrane
4. ribosomes
5. Activities of living things
Autotrophs vs. Heterotrophs Autotrophs - "self feeders" that produce organic compounds
(key example - glucose)
Heterotrophs - organisms who must obtain their energy source by ingesting or absorbing
nutrients from other living things
obligate aerobic bacteria require oxygen
