Key Points

• Microorganisms are divided into seven types: bacteria, archaea, protozoa, algae, fungi, viruses, and multicellular animal parasites ( helminths ).
• Each type has a characteristic cellular composition, morphology, mean of locomotion, and reproduction.
• Microorganisms are beneficial in producing oxygen, decomposing organic material, providing nutrients for plants, and maintaining human health, but some can be pathogenic and cause diseases in plants and humans.

Key Terms

• Gram stain: A method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative).
• peptidoglycan: A polymer of glycan and peptides found in bacterial cell walls.
