Difference Between Fungi and Bacteria

We can see many beautiful and natural things around us, but there are some things that we can not see with our naked eyes. Some of these are microbes that are divided into many types according to their cell type, structure, etc. Fungi and Bacteria are two different and important microbes that exist everywhere in our world, but we can not see them.

Fungi vs Bacteria

The main difference between Fungi and Bacteria is that Fungi is eukaryotic cell means it has proper cell structure and its cell wall contain chitin on the other hand Bacteria is a prokaryotic cell means it does not have a proper structure like it lacks nucleus and cell organelles and its cell wall contain peptidoglycan.

Fungi vs Bacteria

Fungi are a kind of microbes that can be differentiated as they chitin in their cell wall. They are the type of eukaryotic cell, so they have a proper nucleus and many other cell organelles. They are heterotrophs as they are dependent on autotrophs for their food. They secrets digestive enzymes in the environment to get nutrients.

In contrast, Bacteria is also a kind of microbes. They have peptidoglycan in their cell wall. They are categorized as prokaryotes as they don’t have proper cellular structure and they lack nucleus and cell organelles. They are mostly heterotrophs, but there are some autotrophs in Bacteria as well.

Comparison Table Between Fungi and Bacteria

Parameters of ComparisonFungiBacteria
Definition Fungi are eukaryotic cells with chitin in their cell wall.Bacteria are prokaryotic cells with an incipient nucleus.
SizeIts size can be 2 to 10 micrometers.Its size can be 0.5 to 5 micrometers.
ShapeIt can have various shapes, but most of them are thread-like structures.It has three different structures, i.e. round, rod-shaped and spiral.
pHThe best pH for the growth of fungi is 4 to 6 pH.Bacteria prefer a neutral range of 6.5 to 7 pH.
Example Yeast, mushrooms are examples of fungi.Escherichia coli, Salmonella Typhi, Staphylococcus aureus, are examples of bacteria.

What is Fungi?

Fungi are eukaryotic cells that have chitin in their cell wall. Fungi is a plural word. The singular of fungi is a fungus. Some fungi look green in color, but they do not do photosynthesis. They secret digestive enzymes into the environment and then absorb molecules to get nutrients as a portion of food. Hence they are heterotrophs.

Normally, fungi do not move from one place to another, but they grow and spread as means of traveling from one place to another, and some fungi in the form of spores can change their place from time to time with the help of air and water. They also work as decomposers in our ecosystem.

Fungi have some features like plants. For example, they are immobile and, in some cases, bears fruits like mushrooms. So earlier, it was considered in the plant kingdom, but after the invention of molecular methods for phylogenetic analysis, it is found to be different from plants, so now they are in a separate kingdom known as Fungi.

Fungi are also useful for us in many ways. The process of fermentation with the help of fungi helps in food preparations. They are used to prepare loaves of bread, cheese, wine, etc. They are also used to prepare medicines and antibiotics. Even after having lots of uses, some fungi are poisonous, so we should be careful while consuming fungi like mushrooms.


What is Bacteria?

Bacteria word is plural of bacterium. They are microbes categorized as prokaryotes and have an incipient nucleus. They are believed to be the first thing on this earth that has life. Their existence is found to be before 3.5 billion years and can be found in any habitat like air, water, soil, and also in high radiations.

Bacteria are very small in size, it ranges from 0.5 to 5 micrometers. Most of the bacteria are found in three shapes like spherical, rod-shaped, and spiral form. It gets its name from the Greek word “bakterion,” which means “staff, cane,” as the first bacteria to be discovered was rod-shaped.

Bacteria is unicellular and reproduces using an asexual method like binary fission. Bacteria cell life is only 20 to 30 minutes, but they can reproduce very fast. On average, Bacteria can grow double in only 10 minutes. Bacteria can move from one place to another. It has a thread-like structure attached to its body known as flagella that helps it in its movement.

Bacteria can cause many diseases like Tuberculosis, Cholera, Leprosy, Rabies, etc. These diseases can even kill a person, but bacteria also give life to human beings as they are important in the utilization of Vitamin-B12, and there are some good bacteria present in the human body as well.


Main Differences Between Fungi and Bacteria

  1. The main difference between Fungi and Bacteria is that Fungi are a type of eukaryotic cell; on the other hand, Bacteria is a type of prokaryotic cell.
  2. Fungi is multicellular with a defined nucleus, and it also has other cell organelles, whereas Bacteria is unicellular without a defined nucleus, and it also lacks cell organelles.
  3. Fungi have a cell wall made up of chitin. On the other hand, Bacteria have a cell wall made up of peptidoglycan.
  4. Fungi have various shapes, but most of them are in thread-like structure, while Bacteria can be mainly found in three shapes that are, rod-shaped, Spiral, and spherical.
  5. The mode of reproduction in fungi can sexual as well as asexual on the other hand mode of reproduction in bacteria is asexual.


Microbes are not visible to us, but they are everywhere, like fungi and bacteria. Both of them are very small in size. Fungi and Bacteria can cause many diseases in humans as well as animals, but they are also helpful in many ways as they are also used to prepare medicines and food products.

Even after having some similarities, fungi and bacteria are different from each other in many ways. Fungi is eukaryotes with chitin in their cell wall. It has a nucleus and other cell organelles. Bacteria is a prokaryotic cell with peptidoglycan in its cell wall. It lacks a nucleus and other cell organelles.
