Difference Between Multicellular and Unicellular Organisms?
Unicellular Organisms |
Multicellular Organisms |
Made up of a single cell | Made up of a combination of multiple cells |
The whole cell is exposed to the outer environment | Only outer cells are in contact with the environment |
It usually has a shorter lifespan | It has a longer lifespan |
The body formation is quite simple | The body formation is quite complex in nature |
Both eukaryotes and prokaryotes fall into this category | Only eukaryotes come under this category |
The whole life process is controlled by a single cell | Multiple cells together are responsible for proper functioning |
These species are microscopic in nature | Most of these organisms are macroscopic in nature |
Unicellular organisms can be either autotrophs or heterotrophs | Multicellular organisms are both autotrophs and heterotrophs |
Any serious injury to a cell can lead to death | Any physical damage to a cell doesn’t lead to death |
Bacteria, yeast, amoeba, and paramecium falls under unicellular organisms. | Humans, plants, animals, and birds fall under multicellular organisms. |
Difference Between Unicellular And Multicellular Organisms
Every living organism on this planet is made up of cells, and these cells help in the proper functioning of this living organism. There can be one or more cells in a living organism, and an organism with a single cell is known as a unicellular organism, while on the other hand, organisms with multiple cells are known as multicellular organisms.
