Early classification systems consisted of two kingdoms; plantae and animalia. what scientific development allowed taxonomists to establish the monera and protista kingdoms?

Carl Linnaeus developed two Kingdom system of classification which include kingdoms Plantae and Animalia. The kingdom Plantae includes all plants and all animals were included in the kingdom Animalia. The two Kingdom system of classification was used till recently. This system did not differentiates between the eukaryotes and prokaryotes, unicellular and multicellular organisms and photosynthetic such as green algae and non-photosynthetic such as fungi. Therefore, the two kingdom classification seems to be inadequate. Hence, new system of classification done that includes these characteristics. Further, the invention of the electron microscope that lead to the establishment of the other kingdoms. In 1969, R.H. Whitaker proposed a five Kingdom Classification that include kingdoms: Monera, Protista, Fungi, Plantae and Animalia.
