With time, the classification systems have undergone numerous alterations. Aristotle made the first attempt at classification. He divided plants into three categories: trees, shrubs, and herbs.
On the other side, red blood cell presence or absence was used to categorise animals. The known organisms cannot all be categorised using this technique.
As a result, Linnaeus provided a two-kingdom classification scheme. Kingdom Plantae and kingdom Animalia are its constituent parts. However, this approach did not distinguish between eukaryotes and prokaryotes or between unicellular and multicellular creatures. As a result, there were numerous species that fell outside of the two kingdoms.
Thus, in order to classify the three kingdoms, Ernest Haeckel divided unicellular eukaryotic organisms into a separate kingdom called Protista.
