classification of micro org Flashcards
how many types of organisms are microbes classified into?
algae, bacteria, protozoa, fingi, virus
what kind of cellular structures are viruses?
acellular
how do viruses multiply?
inside the cells of living organisms
which are the types micro orgs are classified into on the basis of host
obligate virus- can survive only in the presence of a host
facultative virus- can survive in both thehost or ouside
which kind of organisms are virus based on host?
obligate virus
what is the bacteria called if its infected with virus?
bacteriophage
which type of virus is covid. rna or dna

what is a eukareotic organism?
enclosed in a membrane
what is a prokareotic organsism
not enclosed in a membrane
which type of organism is bacteria/
prokareotic
what are the three components of bacteria?
cell membrane, cytoplasm, genetic material
what is the cell membrane of bacteria made up of
glycalyx, cell wall, plasma membrane
what is glycalyx in bacteria called based on hardness/softness?
hard- capsule
soft- slime layer
what is the cell wall of bacteria made up of?
merein or peptidoglycan
what is the plasma membrane in bacteria made up of?
lipids and proteins
what is cytoplasm
fluid in cell
what does cytoplasm consists of
70 types of ribosomes and gas vacules

near water bodies
where are fungi ususally found
moist and humid places
which is the only different type of organism based on host?
bacteria- prokaryot
