• Monera is a kingdom of procaryotes. Therefore, it is also called or join 's procaryota.
• It includes the most primitive forms of life which developed from an early stock known as progenote.
• Being the earliest forms of life, monerans are adapted to all types of habitats. Population wise they are the most common and the most numerous of all organisms.
• They are found everywhere, wherever organic matter can be present or can be supported- ocean bottoms, below the icebergs, hot springs, dry deserts, dust particles, inside and outside the body of other organisms.
• The air we actually breathe in contains thousands of these organisms generally in their spore stage (the phase of a spore formation or initial stage), in which form they are dispersed. A teaspoon full of soil contains more monerans than the human population in China!
• They have (monerans) very little morphological differentiation. Therefore, it is very difficult to distinguish groups, subgroups, genera and species on the basis of structural and morphological characters alone.
• Mode of nutrition may involve photoautotrophic, saprotrophic, parasitic and chemoautotrophic. Be contain any cell organelles and don't have a well defined nucleus.
Examples include: Epulopscium fishelsoni, Dialister pneumosintes, Thiomargarita ramibiensis, Blue green algae and Mycoplasma (PPLO)(Pleuropneumonia like organisms).
