6. Harmful effects of Micro organisms

7. 1. Microbes are tiny living things that are found all around us and are too small to be
seen by the naked eye.
2. They are also known as microorganisms or microscopic organisms as they could
only be seen under a microscope.
3. They live in water, soil, and in the air.
4. Microbes can be useful as well as harmful.
5. Certain microbes cause severe infections and diseases and can also spoil food and other
materials.
6. Microbes play an important role in maintaining environmental balance.
What is meant by microbes?

8. Types of Microbes
Microorganisms are divided into different types:
1. Bacteria
2. Fungi
3. Viruses
4. Archaea and
5. Protists

9. Types of Microbes : Bacteria
1. Bacteria are unicellular, microscopic, prokaryotic microbes that contain no true
nucleus.
2. They have a flagellum that facilitates locomotion.
3. Bacteria are of different types depending on their shapes and sizes. For eg., spherical-
shaped bacteria are known as cocci; rod-shaped bacteria are known as bacilli; spiral-
shaped, spirilla, etc.
4. They reproduce through binary fission.
5. Few bacteria such as Rhizobium are involved in nitrogen fixation.
6. Bacteria's can be harmful as they can cause harmful disorders such as Tuberculosis

10. Types of Microbes : Fungi
1. Fungi (mushroom, molds, and yeasts) are eukaryotic cells (with a true nucleus).
2. These can be unicellular or multicellular in nature and are found in wet areas
3. These are heterotrophic and cannot synthesize their own food.
4. Yeasts, moulds, mushrooms are some of the important fungi.
5. Few fungi are harmful and cause fungal infections like ringworm. The others are used
in making antibiotics like penicillin.
6. Fungi such as yeast are used in all baking industries and also in the beer and wine
industries
