Answer:

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

They can be autotrophs or heterotrophs They include both autotrophs and heterotrophs

They are microscopic in nature They are macroscopic in nature

Bacteria, amoeba, paramecium, and yeast are examples of unicellular organisms Humans, animals, plants, birds and insects, are examples of multicellular organisms
