Monera,

taxonomic kingdom that comprises the prokaryotes (bacteriabacteria
[pl. of bacterium], microscopic unicellular prokaryotic organisms characterized by the lack of a membrane-bound nucleus and membrane-bound organelles. Once considered a part of the plant kingdom, bacteria were eventually placed in a separate kingdom, Monera.

Previously, archaea and bacteria were combined as prokaryotes (or monera), based largely upon their similar features (or lack thereof) when compared to eukaryotes: the lack of membrane-bound nuclei and organelles, and being generally unicellular [3].
(3) Pese a esta afirmacion, en sus estudios sobre el censo de 1777-1778 Monera se ha cuidado en sugerir que la mayoria de la poblacion del Bolivar Grande no era negra y mulata sino indigena y mestiza, pero no incursiona en estos temas, pues el centro de sus cavilaciones no son estos grupos etnicos sino los afrodescendientes.

Al respecto, Frenguelli expresa: "Dentro del concepto naturalistico del simbolico anillo evolutivo que guio el eximio fundador del Museo y el arquitecto de su magnifico edificio, el arte peruano remata gloriosamente en America ese largo proceso biologico que desde la hipotetica e informe monera debia llegar hasta el hombre dotado de la mas alta capacidad psiquica."

The modern mat-forming cyanobacterium Entophysalis [21] (kingdom Monera) appears to be the morphologically nearest living organism to G.
They are morphological and physiological unions of one or more photosynthetic partner(s), which can be a cyanobacterium from the Monera kingdom or green algae from the Chlorophyta division of the plant kingdom, and one or more fungal partner(s) from the Ascomycetes or Basidiomycetes (Aslan, 2000).
