Question

difference between unicellular and multicellular cell​

Answer 1

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 2

Given:— difference between unicellular and multicellular cell?

To Find:— Diffrence and it's reason and Details

Solution:— The difference between unicellular and multicellular organisms is quite apparent – the number of cells. In other words, each and every living organism is composed of the cell. Based on the number of cells these organisms possess, they can be classified into:

• Unicellular Organisms
• Multicellular Organisms

Read on to explore the difference between unicellular and multicellular organisms in detail:

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:

Unicellular organisms are composed of a single cell

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

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

Cell differentiation is absent

They can be autotrophs or heterotrophs

They are microscopic in nature

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

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

Most are macroscopic in nature

They include both autotrophs and heterotrophs

Cell differentiation is present

Reproduction happens sexually as well as asexually
