Comparison of prokaryotic and eukaryotic cells Flashcards
1
Q
Examples of prokaryotic cells?
A
- Cocci
- Bacillus
- Spirochaetes
- Spirilla
- Vibrios
2
Q
How quickly do prokaryotes replicate?
A
Very quickly - divide every 20 minutes (1 cell)
3
Q
What is the cell wall of prokaryotes made of?
A
Peptidoglycan cell wall (tough)
4
Q
Which part of the prokaryotic cell is toxic & can cause immunological response?
A
Outer membrane / LPS
5
Q
Describe conjugation
A
Donor cells attaches to recipient cell through a pilus (F-pili) and transfers DNA. This enhances natural selection advantage
6
Q
How much genome had E. coli acquired through conjugation
A
1/5th of its genome
7
Q
Which organelles evolved from symbiotic bacteria?
A
Mitochondria and chloroplast.
8
Q
