Describe the characteristics used in hierarchial classification of organisms.

Some characteristics used for the hierarchial classification are:

● Type of cell (Eukaryotic or prokaryotic)- Eukaryotic cell has membrane bound cell organelles and a well defined nucleus which allow cellular processes to be carried out efficiently. While prokaryotic cell lakes membrane-bound cell organelles and have primitive type of nucleus called nucleoid.

● Number of cells present (unicellular or multicellular)- In unicellular organism, single cell performs all vital activities of the organism while in multicellular organism, different cells perform different functions and show division of labour.

● Mode of nutrition (Autotrophic or heterotrophic)- Plants make their own food while animals depend on plants or other animals for their food. For this they will definitely have different body design.
