of the week:
What lies behind us and what lies before us are small
matters compared to what lies within us.
-Ralph Waldo Emerson
Question
of the week: What freshwater mammal is venomous?
Answer to last week's question: How long does it take for food to digest?
The stomach holds two liters of semi-digested food for 3to 5 hours. The stomach slowly releases food to the rest of the digestive tract. 15 hours or more after the first bite started down the alimentary canal, the final residue is passed along to the rectum and is excreted through the anus as feces.
Unit
2:Microscopy, Microbial Cell Biology and Enzymes (Ch3,
4,and first part of Ch 6)
CONCEPT:
MICROSCOPY
-parts
and functions of the compound light microscope
(
eyepiece, objective, fine adjustment, coarse adjustment, diaphragm, body tube,
etc.)
(total
magnification)
-measurements
in microscopy ( millimeter, micrometer and nanometer)
-role
of the oil immersion lens
CONCEPT:
ISOLATING BACTERIAL GROWTH
-pure
culture
-mixed
culture
-streak
plate method
CONCEPT:
PREPARING BACTERIAL SLIDES
-bacterial
smear ( heat fixing, simple stain)
-gram
stain
-gram
positive bacteria
-gram
negative bacteria
-peptidoglycan
cell wall
CONCEPT:
SHAPE OF BACTERIAL CELLS
-cocci
-bacillus
-spirilium
-vibrio
-spirochete
CONCEPT:
ARRANGEMENT OF BACTERIAL CELLS
-"diplo"
as in diplococci
-"strepto"
as in streptococci
-"staphylo"
as in staphylococci
-tetrad
-sarcinae
ETC.
CONCEPT:
EXTERNAL ANATOMY OF THE BACTERIAL CELL (structure and function)
1)
glycocalyx
-slime
layer
-capsule
2)
flagella
parts
( basal body and filament)
location
(monotrichous, lophotrichous, amphitrichous, peritrichous)
3)
fimbrae
4)
pilli
5)
axial filament
6)
peptidoglycan cell wall (gram positive cell wall vs. gram negative cell wall)
7)

CONCEPT:
TRANSPORT IN THE BACTERIAL CELL
1)
passive transport ( diffusion, osmosis, solute, solvent, hypertonic, hypotonic
and isotonic)
2)
active transport
CONCEPT:
INTERNAL ANATOMY OF THE BACTERIAL CELL (structure and function)
1)
circular chromosome ( gene, genome, chromosome)
2)
plasmid
3)
ribosome
