pili, fimbriae, flagellum, capsule, cell membrane, cell wall, plasmid, ribosomes, nucleoid/ DNA chromosome, cytoplasm

Question 6

what does pili do in bacteria

Answer 6

helps with reproduction

Question 7

what does fimbriae do in bacteria

Answer 7

attaches to another bacteria

Question 8

what is a plasmid

Answer 8

short circular DNA, non essential gene that improve survival or competition

Question 9

what does the flagella do in bacteria

Answer 9

allows mobility

Question 10

what are the layers to a bacteria, (outer to inner)

Answer 10

capsule, cell wall, plasma membrane, cytoplasm

Question 11

what 4 things limits reproduction

Answer 11

nutrients
predators
waste build up
competition

Question 12

phage means

Answer 12

virus

Question 13

what are endospores

Answer 13

bacteria goes dormant and become resistant to most stressors only some bacteria
in ice bergs

Question 14

genetic variability 4 things

Answer 14

mutation, transformation, transduction, conjugation

Question 15

mutation is when what is made

Answer 15

errors

changes in DNA sequences

Question 16

ways DNA is shared

Answer 16

transformation, transduction, conjugation

Question 17

transduction

Answer 17

bacteriophage lands on bacteria, abducts some bacteria DNA, breaking the og DNA, some of the OG DNA gets sent off and gives it to a diff. bacteria

Question 18

transformation

Answer 18

eats a plasmid

Question 19

conjugation

Answer 19

attach bacteria together sex pili and transfer plasmid
