ch 13

Question 1

prokaryotic differentiation can be

Answer 1

reversed (not heterocyst and endospores)

Question 2

differentiation

Answer 2

which immature cells become mature cells with specific functions (biofilms, endospores, exospore, yea)

Question 3

exospore

Answer 3

develop outside of cells

Question 4

endospore

Answer 4

for survival, develops inside cell, extremely resistant

Question 5

firmicutes

Answer 5

phylum of bacteria that are able to more endospores (usually +)

Question 6

vegetative state

Answer 6

starts growing until depletion of nutrients, can stimulate spore formation

Question 7

swarmer cell can divide after

Answer 7

differentiating into a sessile stalked cell

Question 8

mycobacteria

Answer 8

in soil, hunts in groups/swarms, glides, eats with antibiotics

Question 9

fruiting body caused

Answer 9

by lack of food

Question 10

fruiting body cells

Answer 10

lyse to provide nutrients for myxospores, will germinate when things look better

Question 11

Nostoc punctiforme differentiation states

Answer 11

three differentiation states: HAH

Question 12

heterocyst

Answer 12

made in low nitrogen- no use photo synths, to preserve nitrogenase activity

Question 13

akinetes

Answer 13

made in low carbon an phosphorus, cut and run, sturdy

Question 14

hormogonium

Answer 14

dispersal form- glides to move

Question 15

Caulobacter crescentus

Answer 15

stalked FREAK

Question 16

all differentiation adaptive responces

Answer 16

biofilms, stalked, myxospore (fruit), Edno spore, exospore, heterocyst, akienet
