The major groups of microorganisms are broadly classified into bacteria, fungi, protozoa, algae and viruses, which are highly diversified in nature. The microorganisms show huge diversity among each other, but these can be broadly grouped into the five major groups that we will discuss in this content.
What are the four main classes of microorganism?
Types of microorganisms
- Bacteria (eubacteria and archaea)
- Algae
- Fungi
What are the 5 different types of microorganisms?
What are the different type of Microorganisms?

What are the classifications of microorganisms?
Microorganisms are very diverse and are found in all three domains of life: Archaea, Bacteria, and Eukarya. Archaea and bacteria are classified as prokaryotes because they lack a cellular nucleus. Archaea differ from bacteria in evolutionary history, genetics, metabolic pathways, and cell wall and membrane composition.
What are microorganisms classified as?
Microorganisms are living organisms that are very minute to be seen by the naked eye and can be classified into four major groups namely bacteria, fungi, protozoa and some algae. See also what is the period of a planet orbiting 3 au
What is the major classification of microorganisms?
Key points. Taxonomy is the classification, nomenclature and identification of microbes (algae, protozoa, slime moulds, fungi, bacteria, archaea and viruses).
What are 4 characteristics of microorganisms?
The biological characteristics of microorganisms can be summarized under the following categories: morphology, nutrition, physiology, reproduction and growth, metabolism, pathogenesis, antigenicity, and genetic properties.
What are types of microorganisms?
The major groups of microorganisms—namely bacteria, archaea, fungi (yeasts and molds), algae, protozoa, and viruses—are summarized below. Links to the more detailed articles on each of the major groups are provided.
How many types of microorganisms are there?
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.
What are 3 characteristics of a microbe?
There are three notable common traits of bacteria, 1) lack of membrane-bound organelles, 2) unicellular and 3) small (usually microscopic) size.
What are the characteristics of major groups of microorganisms?
List The Major Groups Of MicroorganismsBacteriaThey are single-celled disease-causing micro-organisms. They can be spiral or rod-shaped.VirusViruses are disease-causing microbes that reproduce only inside the host organism.AlgaeThey include multicellular, photosynthetic organisms such as Spirogyra, Chlamydomonas, etc.2 more rows
What are the 5 main types of microorganisms?
Microbial diversity is truly staggering, yet all these microbes can be grouped into five major types: Viruses, Bacteria, Archaea, Fungi, and Protists. Let's look at each one in more detail.
What are the characteristics of microorganisms Class 8?
Solution : (a) Microorganisms are ubiquitous, i.e., they are present everywhere.
(b) Microorganisms are useful for production of medicine and alcohol.
(c) They are very small organisms which can not be seen with unaided eyes.
What are the different types of microbes?
Microbes: 4 Most Important Types of Microbes. Some of the major types of microbes are as follows: (a) Prokaryotes or Bacteria (b) Fungi and Protists (c) Protists (d) Viruses.
What are the three types of bacteria?
Bacteria are three basic types of bacteria: (i) Eubacteria. (ii) Archae bacteria who live in extreme environments and. ADVERTISEMENTS: (iii) Cyanobacteria, which are the only living things that can do photosynthesis and fix nitrogen.
What are the major decomposers of organic matter?
Fungi, together with bacteria and protests, are the major decomposers of organic matter on earth. Most fungi are saprobes, that is, they digest nonliving organic matter, such as wood, leaves, and dead animals. However, some fungi are parasites that attack living things and cause disease. Fungi cause many agricultural diseases as well as several ...
How often do bacteria divide?
ADVERTISEMENTS: (iii) Some bacteria can divide every 12 to 20 minutes. Bacteria make proteins called enzymes inside the cell and these travel through the cell wall into the surrounding medium. The enzymes break down the food into tiny subunits which then come into the bacteria cell by osmosis or active transport.
What is the kingdom of Protista?
Kingdom Protista is one of the five biological kingdoms in the formerly used taxonomic classification of organisms (proposed by Robert Whittaker). Protests are grouped into animal-like (protozoa), plant-like (single-celled and some multicellular, eukaryotic algae), and fungus like (i.e. slime molds and water molds).
What are the three basic forms of bacteria?
The small organs and DNA are free-floating within the cell. Bacteria can be as little as round balls, tiny short sticks, or spirals that look like springs. These are the three basic forms. Often these stuck together in long strings or clusters that look like little squares, cubes, or random grapelike clusters.
Which group of organisms lacks a nucleus?
Microbes are any of the group of organisms primarily characterized by the lack of true nucleus and other membrane-bound cell compartments: such as mitochondria and chloroplasts, and by the possession of a single loop of stable chromosomal DNA in the nucleon region and cytoplasm structures, such as plasma membrane, vacuoles, primitive cytoskeleton, and ribosomes.
