Kingdom Monera

Kingdom Monera is a biological kingdom that contains unicellular prokaryotic organisms, such as bacteria and cyanobacteria. They do not have a nucleus or any membrane-bound organelles.

Characteristics

• Unicellular organisms
• Lack a nucleus
• Lack membrane-bound organelles
• Have a cell wall made of peptidoglycan
• Reproduce asexually through binary fission

Importance

Bacteria play an important role in the environment and in human health. They are involved in processes such as decomposition, nitrogen fixation, and fermentation. Some bacteria can be pathogenic and cause diseases, but others can be beneficial and serve as probiotics.

Cyanobacteria are important primary producers in aquatic ecosystems and also play a role in the oxygenation of Earth's atmosphere.
