functions of parts of prokaryotic cell

do in written mode

flagellum

used for locomotion/movement

ribosomes

lacks a plasma membrane

ribosomes

70S (small = 30S, large = 50S)

ribosomes

site of protein synthesis

slime capsule

only bacteria prokaryotic cells have

slime capsule

thick polysaccharide layer

slime capsule

prevents dessication (drying out)

slime capsule

prevents phagocytosis (cell eating)

cytoplasm

site of glycolysis (sugar splitting)

cytoplasm

a little bit of ATP (energy currency) is made

flagellum

the tail

ribosomes

itty bitty dots in the middle

slime capsule

outside layer

cytoplasm

empty space on the inside

cell wall

middle layer

cell wall

rigid outer covering

cell wall

made of peptidoglycan

cell wall

some prokaryotic cells have

cell wall

used for protection/prevention of lysis (cell bursting)

plasma membrane

inside layer

plasma membrane

determines what enters/exits cell

plasma membrane

selectively permeable

plasma membrane

all prokaryotic cells have

pili

hair-like projection

pili

help with bacterial conjugation

pili

help bacteria adhere to surfaces

nucleoid region

squigglies on the inside

nucleoid region

naked DNA not associated with histones

plasmid

big circles on the inside

plasmid

autonomous circular DNA

plasmid

can be transferred to other bacterial cells - horizontal gene transfer
