Study Notes
Microbial Diversity
- Microorganisms are diverse, including bacteria, cyanobacteria, rickettsiae, chlamydiae, fungi, algae, protozoa, and viruses.
- They are microscopic organisms.
Microorganism Contributions
- Many microorganisms are essential for life, maintaining environmental balances and recycling elements (carbon, nitrogen, sulfur, phosphorus).
- They decompose dead organisms.
Microorganism Harm
- Some microorganisms cause infectious diseases.
- They can overwhelm the body through numbers, release harmful toxins interfering with bodily functions.
- Viruses, by replicating within cells, lead to tissue damage.
Bacterial Characteristics
- Bacteria are simple, prokaryotic organisms.
- Prokaryotic cells lack a nucleus and nuclear membrane.
- Different shapes include rods (bacilli), spheres (cocci), and spirals (spirilla or spirochetes).
