There were several characteristics that the scientists kept in mind while classifying, these are mobility, cell structure, cell type, body type, etc.
<h3>What is classification?</h3>
Classification is the grouping of organisms based on similar characteristics which makes them different from other groups.
There are the following characteristics to classify them:
- Mobility: it includes whether the organism is moving or sessile.
- Cell type: it includes eukaryotic or prokaryotic cells.
- Cell structure: it includes whether the cells have a cell wall or not.
- Body type: it includes whether the organism is unicellular or multicellular.
- Mode of nutrition: It includes whether the organism is parasitic, autotrophic, symbiotic, consumer, etc.
Thus, these are the characteristics that the scientists kept in mind before drawing classification.
