Question

difference between single celled and double celled organism

Answer 1

The difference between unicellular and multicellular is some organisms are made up of single cell termed as unicellular while multicellular are made up of two or more cells. Single celled organism is called unicellular organism. They depend on simple diffusion to ride out and live.

Answer 2

The differences are as follows:

• The unicellular body is formed by single cell while body of Multicellular is of multiple cells.

• In unicellular organism the work is divided at the organelle level, while in Multicellular it involves cellular, tissue, organ and organ system level.

• In unicellular organism a single cell is responsible tocarry the life, while in Multicellular organism special cells are focused to carry out distinct cellular duties.

• From all sides the cell of a unicellular organism is exposed to the environment while in Multicellular organism the outer cell face the environment and the inner cells are specialized to do the cell basic function.

• In unicellular organism a simple cellular trauma can cause its death while in Multicellular organism it does not cause the death of the tissue.

• In unicellular organism the cell body cannot attain a large size, due to surface area volume ratio while Multicellular can.

• In unicellular organism the life span is short due to heavy load work while in Multicellular life span is long.

• In unicellular organism the power of division is not lost but in Multicellular organism some non reproductive specialized cells lose this power.
