Life forms on earth are categorized under Five divisions based on nutrition, cell type, the complexity of the structure, energy obtained by them, and much more. The five kingdoms are – Monera, Protists, Fungi, Plantae and Animalia. Though Kingdoms Protista and Monera both comprise of entities that are single-celled, yet they are distinct from each other. Discover the differences between monera and Protista.
- Unicellular entities with a cellular composition of a prokaryote
- Metabolically diverse using several substrates as carbon and energy sources, play a role in carbon and nitrogen cycles
- Their cell wall is rigid, made of peptidoglycan
- They are environmental decomposers and mineralizers exhibiting different modes of nutrition.
- Unicellular entities with a cellular composition of a eukaryote
- Consists of nearly 16 phyla, most of their members are aquatic entities
- Nucleus has several strands of DNA
- They have mitochondria for cellular respiration and few possess chloroplast for photosynthesis
Difference between Monera and Protista
The table below depicts the important differences between Monerans and Protists
|Level of cells||
|Organelles of the cells||Absent||Presence of well-membrane bound organelles, hence well defined|
|Complexity of the structure||Simple||Complex|
|Reproduction – mode||Asexual – budding, binary fission||Asexual or sexual|
|Cell wall||Present||Present, well developed|
|Chloroplast/Mitochondria||Absent||Chloroplast present for photosynthesis. Mitochondria present for cellular respiration|
|Nucleus||True nucleus absent||Present. Nuclei bound with nuclear membrane|
|Flagella and cilia||Absent||Present. Used for locomotion|
|Habitat||Found almost everywhere||Some found in aquatic areas, some in shady places, moist lands so on|
|Classification||Bacteria, Archaebacteria, Cyanobacteria||Algae, Molds, Diatoms, Protozoans|
|Example||Bacillus, Mycobacteria, Sphorobacter||Euglena, red algae, green algae|
