Answer:
Unicellular Organisms
As the name implies, unicellular organisms are made up of a single cell. They are the oldest form of life, with fossil records dating back to about 3.8 billion years ago. Bacteria, amoeba, Paramecium, archaea, protozoa, unicellular algae, and unicellular fungi are examples of unicellular organisms. These unicellular organisms are mostly invisible to the naked eye, hence, they are also referred to as microscopic organisms. Most of the unicellular organisms are also prokaryotes.
Example
- Amoeba
- Euglena
- ParameciumPlasmodium
- Nostoc, Salmonella ( Prokaryotic unicellular organisms)
Multicellular Organisms
Organisms that are composed of more than one cell are called multicellular organisms. Multicellular organisms are almost always eukaryotes. However, bacteria can form large interlinked structures such as colonies or biofilms but these can’t be classified as multicellular organisms.
Example
- All vertebrates and invertebrates
- All angiosperms, gymnosperms and higher land plants
