Difference Between Monera and Protista. The five-kingdom classification system divides the different life forms of earth into five distinct categories such as Kingdom Monera, Protists, Fungi, Plantae, and Animalia. Among them, Monera is the most primitive organism.
The key difference between Monera and Protista is that Monera has a prokaryotic cellular organization, whereas Protista has eukaryotic cellular organization.

| Cellular Level | Monera is unicellular microorganism. | Protista is consist of both unicellular and multicellular organisms. |
| Complexity | Monera has a simple structure and is less complex. | Protista is comparatively complex. |
| Size | Monera contains small micro-organisms. | Protista contains organisms that are larger than Monerans. |
| Nucleus | Monera does not consist of a well-defined nucleus. | Protista has a true nucleus. |
| Organelles | Membrane-bounded organelles are absent in Monera. | Protista contains membrane-bounded organelles like Endoplasmic Reticulum, Golgi apparatus, Mitochondria, Chloroplast. |
| Cell Wall | Monera has a cell wall. | Protista consists of a well-developed cell wall. |
| Presence of Flagella and Cilia | Neither flagella nor cilia are present in Monera. | These are present in some organisms for locomotion; some Protista also has pseudopodia. |
| Mode of Reproduction | The mode of reproduction of Monera is Asexual. | The mode of reproduction of Protista is both Sexual and Asexual. |
| Habitat | They are cosmopolitan, which means Almost all the habitats on earth are occupied by Monera. | They are found partially in aquatic environment, moist soil, shady places, etc. |
| Classification | Monera are classified into eubacteria, archaebacteria and cyanobacteria. | Protista are classified into algae,diatoms, molds and protozoans. |
| Mitochondria/ Chloroplast | Not present. | Present for cellular respiration, chloroplast for photosynthesis. |
| Mode of Nutrition | It can be autotrophic or heterotrophic. | It can be holozoic or parasitic or photosynthetic. |
| Examples | Sporohalobacter, Halobacterium, Clostridium, Mycobacteria, and Bacillus. | Slime Molds, Green Algae, Red Algae, Water Mold, and Euglena. |
