Chapter 11 Characterizing and Classifying Prokaryotes

Question 1

General characteristics of prokaryotes

Answer 1

• most numerous + diverse group of cellular microbes
• thrive in various habitats
• only a few are capable of colonizing humans and causing disease

Question 2

Endospores

Answer 2

• produced by gram-positive bacteria

- each vegetative cell transforms into one endospore

Question 3

Gram positive bacterias that produce endospores

Answer 3

Bacillus and Clostridium

both gram pos rods

Question 4

Reproduction of Prokaryotes + 5 methods

Answer 4

-all reproduce asexually

1 binary fission (most common)
2 snapping division
3 reproducing spores
4 budding
5 viviparity

Question 5

Binary Fission

Answer 5

1 cells replicate DNA
2 cytoplasmic membrane elongate, + separate 2 DNA
3 cross wall forms
4 daughter cells separate

Question 6

Arrangement of Prokaryotic Cells

Answer 6

• results fr 2 aspects of division during binary fission:
• –planes in which the cells divide
• –separation of the daughter cells

Question 7

Bacillus Arrangement

Answer 7

single 
diplo 
strepto (chain)
palisade (spooning style)
v-shape (zig-zag)

Question 8

Answer 8

diplo
strepto (chain)
tetradis (4 square)
sarcinae (8 box)
staphylococci (cluster/grape)
