Characteristics of Monera
Monera (Monos – single) includes prokaryotes and shows the following characters:
- They are typically unicellular organisms (but one group is mycelial). The genetic material in these organisms is the naked circular DNA. A nuclear envelope is absent. Both, ribosomes and simple chromatophores, are the only subcellular organelles in the cytoplasm.
Sap vacuoles do not occur. Instead, gas vacuole may be present.
- The predominant mode of nutrition is absorptive but some groups are photosynthetic (holophytic) and chemosynthetic.
- The organisms are non-motile or move by the beating of simple flagella or by gliding.

Answer:
The Monera Kingdom (or Moneran Kingdom) includes all organisms that have cells that do not contain a nucleus. These cells are also known as prokaryotic cells. These organisms are very simple and are usually only as big as one cell! They are very common on earth and you interact with organisms in this kingdom every day.
Explanation:
Most organisms in the Monera Kingdom are able to reproduce through a process called fission. This means that a single cell copies its DNA and then divides into two identical cells. Because each cell comes from a previous cell, there is not much diversity among certain monera types. Some moneran bacteria replicate every 20 to 40 minutes.
The bacteria of the Monera Kingdom have some very unique and interesting characteristics. They can exist almost anywhere and are very tolerant of both extremely high and low temperatures. Some monera have the ability to move using their flagella but others cannot move on their own.
There are a few monera that can make their own food but bacteria cannot. Bacteria feed on dead and decaying matter. Blue-green bacteria or blue-green algae are a special type of moneran bacteria that can produce its own food through photosynthesis. This is because blue-green bacteria contain chlorophyll.
