Question

differentiate between unicellular and multicellular organisms​

Answer 1

Answer:

Unicellular organisms are made up of a single cell and multicellular organisms are made up of many cells

Answer 2

$\huge\underline\purple{Answer}$

Unicellular organisms: —❤

❥Unicellular organisms are composed of a single cell

❥Irregular in shape

Simple body organization

❥A single cell carries out all necessary life processes

❥The total cell body is exposed to the environment

❥Division of labour is at the organelle level

❥Includes both eukaryotes and prokaryotes

❥A lifespan of a unicellular organism is usually short

❥Injury to the cell leads to the death of the organism

❥Cell differentiation is absent

❥They can be autotrophs or heterotrophs

❥They are microscopic in nature

❥Asexual reproduction is predominant, however, sexual reproduction is also seen (conjugation)

❥Bacteria, amoeba, paramecium, and yeast are examples of unicellular organisms

Multicellular Organisms:—❤

❥Multicellular organisms are composed of more than one cell

❥Complex body organization

❥Multiple cells perform different functions

❥Only the outer cells are exposed to the environment

❥Division of labour is at cellular, tissue, organs and organ system level

❥Includes only eukaryotes

❥Multicellular organisms have a comparatively longer lifespan

❥Injury to a cell does not cause the death of the multicellular organism

❥Multicellular organisms have a comparatively longer lifespan

❥Reproduction happens sexually as well as asexually

❥Cell differentiation is present

❥They include both autotrophs and heterotrophs

❥Most are macroscopic in nature

❥Humans, animals, plants, birds and insects, are examples of multicellular organisms
