Question

Which are the different types of micro-organisms?

Answer 1

Microorganisms can be divided into 5 major groups, like:

Bacteria are the most primitive and diverse unicellular organisms found in the living world. They are prokaryotic in nature as their genetic material, i.e., DNA, is not enclosed within a nuclear membrane. Because of their unique biochemical pathways and properties, they are of high economic importance to human beings.

Fungi: Fungi is a group of eukaryotic, unicellular, as well as multicellular, non-photosynthetic organisms that includes mushrooms, moulds and yeasts. These organisms have a rigid cell wall made up of chitin and are found in diverse shapes and sizes.

Algae: Algae are a diverse group of aquatic organisms that have the ability to conduct photosynthesis.

Protozoa: Protozoa are a group of unicellular micoorganisms that are non photosynthetic in nature. Many protozoa cause disease in animals and humans.

​Viruses: Viruses are ultramicroscopic and non-cellular organisms. They have a simple structure, having genetic material coated by a protein coat. They are obligate parasites and highly pathogenic.
