Difference Between Unicellular And Multicellular Organisms
As stated initially, one major difference between unicellular and multicellular organisms is the cellularity or the number of cells. Read on the explore more differences between the two:
Unicellular Organisms Multicellular Organisms
Unicellular organisms are composed of a single cell Multicellular organisms are composed of more than one cell
Irregular in shape Have a definite shape
Simple body organization Complex body organization
A single cell carries out all necessary life processes Multiple cells perform different functions
The total cell body is exposed to the environment Only the outer cells are exposed to the environment
Division of labour is at the organelle level Division of labour is at cellular, tissue, organs and organ system level
Includes both eukaryotes and prokaryotes Includes only eukaryotes
A lifespan of a unicellular organism is usually short Multicellular organisms have a comparitively longer lifespan
Injury to the cell leads to the death of the organism Injury to a cell does not cause death of the multicellular organism
Reproduce by asexual reproduction Reproduction happens sexually as well as asexually
Cell differentiation is absent Cell differentiation is obvious
