The kingdom Monera are the first life form to have evolved on planet earth. Organisms such as bacteria are classified under this kingdom, called Monera.
Some of the important and significant characteristics of Monera are that they are about 1 micrometer in size and complex as living molecules.
They are unicellular, lack nuclei and many other cell organelles and they have a cell wall made of polysaccharides with polypeptide cross links with a chemical called peptidoglycan.
Their plasma membrane is made of lipids and proteins.
They usually photosynthesise to get their supply of food.
Their cell structure is usually round, rod-like or spiral.
They reproduce asexually by binary fission or sexually by conjugation.
Their process of digestion and circulation is carried out through diffusion.
Examples of Monera include Actinomyces, Bacillus, Bactericides, Bordetella and Chlamydia
- Most reproduce by binary fission.
- Some protists perform photosynthesis like plants while others move around and act like animals, but protists are neither plants nor animals.
Examples of protists include amoeba, paramecium and kelp.
- Eukaryotic; complex and have membranes
- Non-vascular organisms; no blood vessels
- Reproduce by means of spores usually dispersed by wind
- Able to produce both sexual and asexual spores
- Lack chlorophyll; unable to make food like plants
- Stores food in the form of glycogen
- Grow hyphae which form a mycelium
- Digests food before ingestion unlike other heterotrophic organisms (eg. animals)
- Cell wall made of chitin
