Prokaryotae Kingdom
Prokaryotae Kingdom
A kingdom of single-celled organisms that lack a nucleus and other membrane-bound organelles. They include bacteria and archaea.
What are some characteristics of prokaryotes?
What are some characteristics of prokaryotes?
Prokaryotes are single-celled organisms that can obtain nutrients through absorption, photosynthesis, or chemosynthesis. They thrive in diverse harsh environments, including salty lakes, hot springs, wetlands, deep sea vents, and ocean depths.

Study Notes
Classifying Kingdoms
- The system used in this book joins different biology fields
- Algae scientists have their own algae classification system
- Animal/plant naming uses different rules
- The six kingdoms system isn't the perfect representation of living things, but it helps show relationships
Table of Six Kingdoms
| Kingdom | Phylum/Division | Class | Example |
|---|---|---|---|
| Bacteria | Aphragmabacteria | Various | Mycoplasma |
| Bacteria | Aphragmabacteria | Various | Aphragmabacteria |
| Bacteria | Aphragmabacteria | Various | Halobacteria |
| Bacteria | Aphragmabacteria | Various | Halobacterium |
| Bacteria | Aphragmabacteria | Various | Methanoarchaea |
| Bacteria | Aphragmabacteria | Various | Methanobacterium |
| Bacteria | Aphragmabacteria | Various | Methanopyrus |
Characteristics of Bacteria
- Single-celled organisms
- Some absorb nutrients from their environment
- Others perform photosynthesis or chemosynthesis
- Often found in harsh environments (salty lakes, hot springs, marshes, deep sea vents)
Other Kingdoms
- Protists: Single-celled, absorb food, come in various shapes (round, spiral, rod-like), some form colonies
- Protozoa: Single-celled, consume food; many are free-living, some are parasitic
- Ciliates: Single-celled, consume food, many cilia (hairs) for movement
- Spores: Single-celled, parasitic, no movement
