Study Notes
Micro
-
Definition: Prefix meaning "one millionth" (10^-6) in the International System of Units (SI) or indicating small size in general context.
-
Microorganisms:
-
Types:
- Bacteria: Single-celled, vital for nutrient cycling.
- Archaea: Similar to bacteria but genetically distinct; often extremophiles.
- Fungi: Includes yeast and molds; important for decomposition.
- Protozoa: Single-celled eukaryotes; can be pathogenic.
- Viruses: Acellular entities that require a host to replicate.
-
Roles:
- Decomposition and nutrient recycling.
- Symbiosis in ecosystems (e.g., nitrogen-fixing bacteria).
- Pathogens causing diseases in humans, animals, and plants.
-
Types:
-
Microbiology:
-
Branches:

- Genetic Engineering: Techniques like CRISPR for gene editing.
-
Genetic Exchange:
-
Microbial Ecology:
-
Interactions:
- Symbiosis: Mutualism, commensalism, parasitism.
- Competition: Nutrient and habitat competition between microorganisms.
- Biogeochemical Cycles: Microbes play crucial roles in carbon, nitrogen, and sulfur cycles.
-
Interactions:
