Explanation:

Unicellular organisms are living organisms that consist of only one cell. They are the simplest form of life and can be found in all types of habitats, including soil, water, and air. Examples of unicellular organisms include bacteria, protozoa, and yeast.

What is a unicellular organism?

A unicellular organism is an organism that consists of only one cell. This means that all the functions of life, such as feeding, respiration, and reproduction, are carried out by a single cell. Unicellular organisms can be found in all types of habitats and can be either autotrophic or heterotrophic.

Examples of unicellular organisms:

Some examples of unicellular organisms are:

- Bacteria: These are single-celled organisms that are found almost everywhere on Earth. They can be found in soil, water, and even in extreme environments like hot springs and deep-sea vents.

- Protozoa: These are single-celled organisms that are found in water and soil. They are usually motile and can move around using hair-like structures called cilia or flagella.

- Yeast: These are single-celled fungi that are used in the production of bread, beer, and wine. They are also used in genetic research because they are easy to manipulate in the laboratory.

Conclusion:

Unicellular organisms are the simplest form of life and can be found in all types of habitats. They consist of only one cell and carry out all the functions of life within that cell. Examples of unicellular organisms include bacteria, protozoa, and yeast.

Yes yeast is a unicellular organism
