Why are microbes essential to the survival of life on earth and what did they play in the ecosystem?
Microbes produce oxygen via photosynthesis, soil via decomposition activities, and food for humans. 
What is a ribocyte?
1st RNA based cell
What is a ribozyme?
a RNA version of an enzyme, the molecule in ribosomes that catalyzes peptide bonds to make protein (aka peptidyl transferease)
coccus
sperical (both Archaea and bacteria)
bacillus
rod (both Arachea and bacteria)
vibrios
curved rod
spirillum
spiral rod (stiff with traditional flagella)
spirochete
helical rod (flexible with endoflagella)
strep
chains
staph
clusters
tetrads
four cells in a square
packets
eight or more cells arranged as a cube
layers of Gram positive (3 layers)
1. thick peptidoglycan (60-90%)
2. periplasmic space that contains digestive enzymes
3. plasma membrane
what does the "E" represent in E. Coli
Escherichia
What is MRSA
Methicillin-resistant Staphylococcus aureus
What is VRE
Vacnomycin-resistant enterococci
What is VRSA
Vancomycin-resistant Staphylococcus aureus
Which scientist's boiled and sealead flask of broth failed to generate support for biogenesis, the "vegetative force" couldn't get into the flask.
Lazzaro Spallanzani
Which scientist demonstrated that maggots (macroscopic organisms) do no spontaneously generate?
Francesco Redi
Which scientist developed a microscope powerful enough to allow microbes to be seen?
Anton van Leeuwenhoek
Which scientist proved the connection between microbes and disease?
Robert Koch
This scientist's discovery of endospores resulted in the final overthrow of the idea of spontaneous generation
Ferdinand Cohn
Which scientist was a contemporary of Matthias Scleiden and Rudolf Virchow and along with them, contributed to the development of cell theory?
Theodor Schwann
Which scientist used a swan-like necked flask to disprove the idea of Spontaneous Gerneration of microbes?
Louis Pasteur
Which scientist discovered a way to eliminate "endospores" from growth media?
John Tyndall
Which scientist contributed to the development of the growth of media and pure culture techniques we use in class?
Robert Koch
This organelle is the site of protein synthesis
ribosome
This organelle would house the genome of an animal cell
nucleus
This organelle is where ATP is generated in an animal cell
mitochondria
This organelle is only found in plant and algae cells
chloroplast
Which organelle consists of RNA and protein
ribosome
Which organelle is not membrane bound
ribosome
How are biofilms generated?
1. Initial attachment
2. Irreversable attachment
3. Maturation I
4. Maturation II
5. Dispertion
( Biofilms form when bacteria adhere to surfaces in some form of watery
environment and begin to excrete a slimy, gluelike substance that can stick to
all kinds of materials)
Where do biofilms generate?
Biofilms happily colonize many household surfaces in the bath and kitchen,
including toilets, sinks, countertops, and cutting boards
What is the evolutionary relationship between Archaea and the cells in the other two domains
Archaea and eubacteria had a common ancestor, later on eukarya branched off of Archaea
What are the 2 bacterial genuses that produced endospores?
Sporosarcina Bacillus and Clostridium
Which domain was the first domain to evolve on this planet?
Archaea
If you receive an envelope filled with endospores, cells belonging to this domain will probably infect you
Bacteria
The cells in this domain have membrane bound organelles
Eukarya
Cells in this domain have their DNA wrapped around histone-like molecules
Archaea
Most of the cells in this domain use plasmids to share DNA
Archaea and Bacteria
Cells in this domain have 80S ribosomes
Eukarya
All cells in this domain have a cell membrane with sterols
Eukarya
Cells in this domain have a unique cell membrane without fatty acids
Archaea
Cells in this domain usually have cell walls of petidoglycan
Bacteria
Cells in this domain have a cell wall that includes a S layer
Archaea and Bacteria
Cells in this domain have a cell wall that may include an outer lauer of lipopolysaccharide
Bacteria
Cells in this domain have a glycocalyx
Archaea, bacteria, and Eukarya
Cells in this domain often use undulipodia to move from place to place
Eukarya
Which stain just stains the background, not the organism
Negative stain
