Solution:

: The kingdom monera includes all prokaryotes (simplest, microscopic) - mycoplasma (smallest organism), bacteria (archaebacteria- ancient and primitive forms and eubacteria - true bacteria), actinomycetes (mycelial) and cyanobacteria. Progenote is considered to be an ancient form from which bacteria are evolved. Monerans are ubiquitous (i.e., present everywhere).
