Question

What are the major groups of microorganisms?

Answer 1

There are five major groups of microorganisms:

1. Bacteria: They are single-celled disease-causing microorganisms. They can be spiral or rod-shaped.
2. Fungi: They are mostly multicellular disease-causing microbes. Bread moulds are common examples of fungi.
3. Protozoa: They mainly include organisms such as Amoeba, Plasmodium, etc. They can be unicellular or multicellular.
4. Algae: They include multicellular, photosynthetic organisms such as Spirogyra, Chlamydomonas, etc.
5. Viruses: Viruses are also microscopic but different from other microorganisms. They reproduce only inside the host organism's cells, which may be a bacterium, plant, or animal.
