1 micro-meter organism
2 types of prokaryotic cells.....bacteria & archaea........how are different & simular?
Simular- they both possess prokaryotic cells diff- They have different chemicals in their cell walls.
ability to distinguish between two points
Cell wall made of cellulose, photosynthetic
allow a cell to survive
Prokaryote without peptidoglycan cell wall
Cell wall made of peptidoglycan
bond between electron donor and acceptor
bond between H and O in H2O
bond between molecules of water
capitalized in a scientific name
cell wall of chitin
dehydration or synthesis
chemical process that creates smaller molecules
hydrolysis or digestion
chemical reactions in a cell
coined the word vaccination to honor another scientist
contains 3 fatty acids and glycerol
contains amino and carboxyl group
Corkscrew or curved
decomposition of molecules and synthesis of new molecules from their subunits
Describe 2 types of endocytosis
phagocytosis-used by WBC to destroy bacteria & foreign substances.pinocytosis-the plasma membrane folds inward, bringing extracellular fluid into the cell, along w/whatever substances are dissolved in the fluid.
Determine atoms reactivity
Developed vaccination against smallpox
Disproved spontaneous generation
emerging infectious disease
endospores is called
engulfing of large particles through plasma membrane
Even though the germ theory of disease was not demonstrated until 1876, why did Semmelweis (1840) and Lister (1867) argue for the use of aseptic techniques?
Though the theory was not completely known, Semmelweis and Lister observed healthier or more positive results from their patients with their new procedures.
Find at least three supermarket products made by microorganisms. (Hint: The label will state the scientific name of the organism or include the word culture, fermented, or brewed.)
Yogurt, beer, cheese.
first stain in gram stain
First to use disinfectants in surgical procedures
Formation of new cell from an endospore is
formed by shared electrons
forms secondary structure of proteins
cell wall made of chitin
Giraffes, termites, and koalas eat only plant matter. Since animals cannot digest cellulose, how do you suppose these animals get nutrition from the leaves and wood that they ingest?
The animals have cellulose-degrading bacteria in specialized stuctures in the digestive tracts.
had monomers of amino acids
has membrane bound nucleus
have DNA or RNA
Helminths belong to this kingdom
helps a stain stick to an organism
How did the theory of biogenesis led the way for the germ theory of disease?
Koch would then be able to hypothesize what may be causing a disease (a living organism) enabling him to conjecture what he should observe in a sick host.
In Gram stain, one step could be omitted and still allow between gram-positive and gram-negative cells. What is that one step?
Step 1 can be omitted. Safranin can be omitted.
includes bacteria and archea
last name is a scientific name
lens in the eyepiece
lens in the nosepiece
light silhouette of organism seen against dark background
main component of plasma membrane
maximum magnification 2000x
microscope with greatest magnification and resolution
molecule that releases hydrogen ions
monomer of nucleic acid
most common microscope in microbiology
passive diffusion that requires transporter proteins
People believed all microbial disease would be controlled during the twentieth century. List three reasons why we are identifying new diseases now.
Microorganisms are ubiquitous; it would take a great effort to catalogue all the species.Microorganisms mutate into different strains; thus new diseases are created. With the leaps of technology, people may now engineer new strains.
products revert to reactants
Prokaryote with cell wall of peptidoglycan
protect bacteria from antibiotics
unicellular, complex cell structure lacking a cell wall
proved that microorganisms can cause disease
provides some protection from phagocytes
red stain used in acid-fast process
site of protein synthesis
smallest unit of life
smallest unit of matter
atom or element
sugar, cellulose, chitin
The smallest eukaryotic cell is the motile alga Micromonas. What is the minimum number of organelles this alga must have?
Nucleus, mitochondrion, chloroplast, flagellum
transports a substance down the concentration gradient
transports a substance from a lower to a higher concentration
Unicellular prokaryote living in extreme environments
used for motility
Used the first synthetic chemotherapeutic agent
used to keep a sterile environment
utilizes UV source
not composed of cells
What happens to the relative amount of unsaturated lipids in the plasma membrane when E.Coli grown at 25 C are then grown at 37 C?
The amount of unsaturates decreases, and the amount of saturated lipids increases
when E. Coli..........Which requires ATP?
increases intracelluar solute concentration bringing it closer to that of the hyperosmotic excellular environment & thus reducing the severity of plasmolysis.
