Chapter 11 Characterizing and Classifying Prokaryotes Flashcards
1
Q
General characteristics of prokaryotes
A
- most numerous + diverse group of cellular microbes
- thrive in various habitats
- only a few are capable of colonizing humans and causing disease
2
Q
Endospores
A
- produced by gram-positive bacteria
- each vegetative cell transforms into one endospore
3
Q
Gram positive bacterias that produce endospores
A
Bacillus and Clostridium
both gram pos rods
4
Q
Reproduction of Prokaryotes + 5 methods
A
-all reproduce asexually
1 binary fission (most common) 2 snapping division 3 reproducing spores 4 budding 5 viviparity
5
Q
Binary Fission
A
1 cells replicate DNA
2 cytoplasmic membrane elongate, + separate 2 DNA
3 cross wall forms
4 daughter cells separate
6
Q
Arrangement of Prokaryotic Cells
A
- results fr 2 aspects of division during binary fission:
- –planes in which the cells divide
- –separation of the daughter cells
7
Q
Bacillus Arrangement
A
single diplo strepto (chain) palisade (spooning style) v-shape (zig-zag)
8
Q
Coccus Arrangement
A
diplo strepto (chain) tetradis (4 square) sarcinae (8 box) staphylococci (cluster/grape)
9
Q
3 Domains of Life
A
Archaea
Bacteria
Eukaryotes
