Answer 2

★ Life on earth evolved from a single cell millions of years ago. These single cells are known as unicellular organisms. All the life processes in a unicellular organism, including digestion, excretion, respiration, occur within a single cell. These cannot be seen by naked eyes and are hence called microorganisms. There are several kinds of unicellular organisms such as bacteria, protozoa, algae, fungi, etc.

★ There are two types of unicellular organisms:

• Prokaryotes

• Eukaryotes

★ The characteristics of unicellular organisms are as follows:

1. The unicellular organisms usually reproduce by asexual means.

2. They can be eukaryotes or prokaryotes.

3. They are found in almost all habitats, from hot springs to frozen tundra.

4. They possess whip-like structures for movement.

5. The nutrients enter or leave the cell by the process of diffusion.
