Monera is a term used in biology to refer to a kingdom of organisms that includes bacteria and blue-green algae. These are unicellular prokaryotic organisms, which means that they lack a nucleus and other membrane-bound organelles. They are typically small in size and have a simple morphology. Monera organisms are known for being some of the most abundant and diverse organisms on Earth. They are found in virtually every habitat, from the depths of the ocean to the soil in your backyard. Although they are often referred to as "simple" organisms, Monera play critical roles in many ecological processes, including nutrient cycling, nitrogen fixation, and decomposition.
