Chemotrophs - Answer -Energy source is from oxidation of chemical compounds

,Lithotrophs - Answer -Electron source from reduction of inorganic substances

Organotrophs - Answer -Electron source from organic compounds

Passive diffusion - Answer -Movement of small molecules across a cellular membrane
to go from high concentration to low with the potential graduation - no energy required

Facilitated diffusion - Answer -Use of a carrier protein to assist the transportation of
molecules across the cellular membrane

Pure culture - Answer -Assumption that all the cells grown on the plate have arose from
one single ancestor cell

Defined Media - Answer -Media in which all components of the mix are known

Complex Media - Answer -Media in which all components are not known

Selective Media - Answer -Media favors growth of specific microorganisms

Differentiated Media - Answer -Media can will visually distinguish between groups of
bacteria based on biological characterisitics

Binary Fission - Answer -Reproductive strategy of most haploid bacteria/archaeal cells
to create identical cells

1) cell elongates
2) replicates their chromosome
3)divides down middle with one chromosome in each new half

Bacterial Growth Stage 1: Lag Phase - Answer -Time after the new introduction of
bacteria on a new medium with no growth

Bacterial Growth Stage 2: Exponential Phase - Answer -Microbes are now growing at a
constant rate at maximum dividing rates

Bacterial Growth Stage 3: Stationary Phase - Answer -Population growth ceases and
the growth curve levels off

Bacterial Growth Stage 4: Death Phase - Answer -Decrease in viable microorganisms
due to depletion of sources (media, oxygen, food)
