Answer: Monera is a kingdom that contains unicellular organisms with a prokaryotic cell organization, such as bacteria. They are single-celled organisms with no true nuclear membrane. The taxon Monera was first proposed as a phylum by Ernst Haeckel in 1866
Explanation: just look it all up on google or other websites
Monera is a kingdom of organisms which lack a defined nucleus of organelles, nor do any of them show multi-cellular body designs. They show diversity based on many other characteristics. Some of them have cell walls while some do not. The mode of nutrition of organisms in thie group can be either by synthesizing their own food (autotrophic) or getting it from the environment (heterotrophic). This group includes bacteria, blue-green algae (cyanobacteria) and mycoplasma.
