the site of protein synthesis
ribosomes
contain storage forms of food
granules
referred to as a slime layer
capsule
function is to transfer DNA

no
allow the bacteria to be motile
flagella
what gives the bacteria its shape
cell wall
site of antibiotic activity
cell wall
kills bacteria by not allowing the cell wall to grow and prohibits cell division

lysozyme
a bacteria without a cell wall
protoplast
refers to all the fluid substances enclosed in the cell membrane

generation time
average generation time. varies from 10 minutes to 3 days.
20 minutes
average generation time for tb
3 days to 6 weeks
conditions that allow bacteria to grow fast
optimal conditions
no increase in number: increase in size

good for media that cannot be boiled or autoclaved
filtration
discovery of viruses
filtration
5 criterias of biological organisms
1 they must reproduce
2 they must ingest food substances and metabolize the food for energy and growth
3 they must excrete waste
4 they must react to changes in the environment (known as irritability)
5 they are susceptible to mutations

no
do viruses ingest food or excrete waste
no
do viruses reproduce and are susceptible to mutation
yes
