Document Summary

Microbiology: study of small living beings: bacteria, archaea, viruses, protozoa, the lower fungi (yeasts and molds, algae, some other groups of single celled creatures. Types of microorganisms: cellular organisms (definitely alive) Eukaryotes (normal nucleus: subcellular aggregates of molecules (alive???) Viruses differ from bacteria in that they are not cellular organisms. Viruses consist of some genetic material, which may be either dna or rna, surrounded by a coat of protein which is also known as the capsid. Some animal viruses also have a membrane-like envelope of lipids an dproteins but many viruses lack this feature. Viruses lack ribosomes and trnas, so they cannot synthesize proteins on their own. Viruses contain few or no enzymes, they lack metabolic pathways. Viruses lack atp and have no means of generating atp. They must be inside a living host cell in order to have life-like functions such as reproduction.
