Question

in the modern classification system, of the six kingdoms now recognized -
two are eukaryotes and four are prokaryotes
four are eukaryotes and two are prokaryotes
four are macroscopic and two are microscopic
two are eukaryotes and four are prokaryotes

Explanation:

In the modern six - kingdom classification system (Animalia, Plantae, Fungi, Protista, Archaebacteria, Eubacteria), Archaebacteria and Eubacteria are prokaryotes (they lack a true nucleus and membrane - bound organelles). Animalia, Plantae, Fungi, and Protista are eukaryotes (they have a true nucleus and membrane - bound organelles). So, four kingdoms (Animalia, Plantae, Fungi, Protista) are eukaryotes and two kingdoms (Archaebacteria, Eubacteria) are prokaryotes. Also, the classification is not based on macroscopic or microscopic nature as there are both macroscopic and microscopic organisms in different kingdoms.

Answer:

Four are eukaryotes and two are prokaryotes.
