Microbial physiology Flashcards
the scientific study of functions and mechanisms in a living system
physiology
concerns the vital life of processes of microorganisms
microbial physiology
bacterial physiology includes what?
- nutrition
- environmental factors affecting survival of bacteria
- growth and multiolication
- metabolism
bacterial growth
increase in size and no. of cells
group of cells large enough to be seen without a microscope
colony
bacteria which can synthesize their own food
ex: algae, cyanobacteria
autotrophs
bacteria which cannot synthesize their own food
heterotrophs
what are the different types of heterotrophic bacteria?
- parasitic
- saprophytic
- symbiotic
they derive their food from living organisms
parasitic
they feed in dead and decaying organic matter
saprophytic
they live in a symbiotic association with other organisms
symbiotic
what are the organism that produces their own food
- plants
- algae
- some bacteria
- phytoplankton
what are the organism that does not make their own food
- fungi
- animals
- most protozoa
- most bacteria
uses photosynthesis or chemosynthesis
autotrophs
get proteins and energy
heterotrophs
how do autotrophs produce their own food? (plants and bacteria)
plants
- photosynthesis
-chloroplasts
bacteria
- chemosynthesis
