🔑 Key Concepts & Definitions

• Microorganism: A microscopic organism that includes bacteria, viruses, fungi, and protozoa, often invisible to the naked eye, playing vital roles in ecosystems and human health.
• Bacteria: Single-celled prokaryotic organisms characterized by lack of a nucleus, with diverse shapes, metabolic pathways, and cell wall structures.
• Virus: An infectious agent composed of genetic material (DNA or RNA) enclosed in a protein coat (capsid), requiring a host cell for replication.
• Fungi: Eukaryotic organisms with chitinous cell walls, including yeasts (unicellular) and molds (multicellular), involved in decomposition, fermentation, and some diseases.
• Pathogen: A microorganism capable of causing disease in a host organism.
• Protozoa: Single-celled eukaryotes that can move and ingest food, some of which are pathogenic to humans.
