Distinguish between unicellular and multi-celluar organisms?
Answers
Answer:
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. ... Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions.
Answer and Explanation:
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.
Examples of Unicellular Organisms
Some of the examples of unicellular organisms are:
- Amoeba
- Euglena
- Paramecium
- Plasmodium
- Nostoc, Salmonella ( Prokaryotic unicellular organisms)
- Protozoans, Fungi, Algae ( Eukaryotic 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.
Multicellular Organisms Examples
Some of the examples of multicellular organisms are listed below:
- All vertebrates and invertebrates
- All angiosperms, gymnosperms and higher land plants
