Answer:

The distinguishing features of monera are as follows:

  • Monera are about 1 micrometer in size and complex as living molecules.

  • The Monera cell structure is mostly unicellular and some organisms orm groups or filaments.
  • These organisms are the simplest prokaryotic cell structures.

  • The cell structure lacks nuclei and many other cell organelles.

  • They have a cell wall made of polysaccharides with polypeptide cross links with a chemical called peptidoglycan.

  • They lack enclosed sub-cellular organelles like mitochondria and only have ribosomes.

  • The genetic material DNA is contained in the cytoplasm called nucleoid.

  • Many bacterial species contain rings of DNA called plasmids.The cytoplasm is enclosed by plasma membrane that lies beneath the cell wall.

  • The plasma membrane is made up of lipids and proteins.Some Monera have hair like pilli for adhesion or tail-like flagella for locomotion.

  • The source of nutrition for these organisms is usually photosynthesis or chemosynthesis.

  • The characteristics also include the shape of the cell that includes round (cocci), rod-like (bacilli), or spiral (spirochetes or spirilla).

  • Reproduction is asexually through binary fission or sexually by conjugation. The process of circulation and digestion is carried out through diffusion.

  • The Monera kingdom includes all bacteria that may infect animals, humans, and plants. But most of the members are termed as beneficial bacteria, rather than pathogenic bacteria.

  • The Monera kill organisms causing pathogenic diseases, breaks down algae, and can even recycle chemical pollutants like hydrogen sulfide and ammonia.

  • Bacteria that grow in the root nodules help break down atmospheric nitrogen into fixed nitrogen.

  • The bacteria that forms the natural flora of the intestines are very important for proper digestion.

  • One of their many characteristics also includes production of antibiotics likes streptomycin that is useful for treatment of infections.

  • Monera can be identified by their characteristic of cell wall that can be or not stained by Gram staining.

  • Most of the Moneora can survive harsh environment by producing spore coat.
