The 5 Kingdoms of Organisms

HISTORY

Robert whttaker published a proposed five kingdom system for the classifcation of the organisms in the year 1969.

He placed the most single celled organism into either prokaryotic monera or the eukaryotic protista.

The other three kingdoms are eukaryotic fungi, animalia and plantia.

Monera

Monera is a taxonomic group in biological classification originally understood as one of the five biological kingdoms.Sometimes called as prokaryota or prokaryotae.

Originates from the primitive of life known as progenote

Examples of this kingdom are bacteria, cyanobacteria, mycoplasma,ect.

And they are present in everywhere.

What are PROKARYOTES? What are

PROKARYOTES?

Archaebacteria (the ancient type) are the oldest prokaryotes. Their characteristic feature is the absence of peptidoglycan in the cell wall and the presence of the proteins and polysaccharides.

Eubacteria (the true type) are characterized by how they metabolize resources, their means of motility, and their shape.

c.Spirillium (spiral)

a.Cocci (spherical)

b.Bacillus (rod shape)

Eubacteria is further devided into two, bacteria and caynobacteria

BACTERIA are the organisms which belongs to kingdom monera have cell wall made of peptidoglycan, cannot be seen in naked eye and lack membrane bound organelles.

CYANOBACTERIA are also know as blue green algae, they are also gram positive prokaryotes. They are hpotosnthetic and have pigments like chorophyll, along with phycobillins
