BIO 204 CH. 4
1. What are the two types of cells?: Prokaryotic and Eukaryotic
2. What are the two prokaryotic domains and kingdoms?: Bacteria and Archaea
3. Define prokaryote: Single-celled, has no membrane-bound nucleus, and has little evidence of internal
structure
4. What components of the prokaryotic cell are external to the cell wall?: -
Glycocalyx
- Flagella
- Pili
- Fimbriae
5. What are the two forms of glycocalyx?: Capsule & Slime layer/biofilm
6. What is the appearance of the capsule?
What are the functions of the capsule?: Appearance: organized & thick
Function: protects against phagocytosis, increases virulence
1/4
, 7. What is the appearance of the slime layer?
What are the functions of the slime layer?: Appearance: loose & thin
Function: protects against desiccation, traps nutrients, cell binding, & adhesion to surfaces
8. What are the parts of the bacterial flagella?
What is the function of each part?: Filament: locomotion
Hook: attaches the filament to the motor
Basal body: anchors the hook & filament to the cell wall and plasma membrane
9. What are the arrangements of flagella?: - Monotrichous
- Amphitrichous
- Lophotrichous
- Peritrichous
10. What is a monotrichous flagella?
Amphitrichous flagella?
Lophotrichous flagella?
