Kingdom Monera comprises of the bacteria and cyanobacteria that are usually known as blue-green algae. While only bacteria are prokaryotic which lack a true nucleus, (which means without a nuclear membrane). The only prokaryotic plant kingdom is Monera. Bacteria were the first cellular organisms to develop on the earth since afterlife initiated around 3.5 billion years ago and they are the single cellular organisms on the planet earth for about the next two billion years.
The bacterium which is a single-celled has a cell wall made of peptidoglycan compound enclosing the cell membrane and a single circular chromosome. The cell contains ribosomes, but it lacks membrane-bound organelles.
Cell wall: It is the outermost covering of a cell. The prokaryotes possess a rigid cell wall that gives shape and protects the cell wall. The cell wall is made up of a chemical called peptidoglycan which is unique to lipids, bacteria, polysaccharides and some proteins.
During the warm humid season, chapati, bread slices, leather shoes, and belts, develop a dusty layer on them. In flower beds and lawns, mushrooms pop out and these are called as fungi.
The fungi can be classified into five main kinds. They are:
