Which of the following kingdoms contains prokaryotes?
A.Protista
B. Eubacteria
C. Plantae
D. Fungi

Classification is a science of classifying organisms based on their similarities and differences. Organisms are classified into six major kingdoms, namely; kingdom Plantae, kingdom Eubacteria, Kingdom Animalia, Kingdom Fungi, kingdom Protista, and kingdom archaebacterial.

The members of this kingdom have the following characteristics;

They are prokaryotes
They possess cell walls that are made up of peptidoglycan
Organisms are unicellular and complex
Organisms in this kingdom are found everywhere
These organisms have flagella
They have ribosomes for protein synthesis
They lack membrane bound organelles such as lysosomes, Golgi apparatus, mitochondria, etc.

These are organisms that contain membrane bound nucleus and membrane bound organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, etc.

These are organisms that lack nucleus membrane and a nucleus together with membrane bound organelles. They include lower organisms such as bacteria and Archaea.
Archaea and bacteria are examples of prokaryotes since they lack nucleus and other membrane bound organelles such as mitochondrion, endoplasmic reticulum, etc.

Archaea cell wall contains while the cell wall of bacteria contains peptidoglycan
Bacteria can form spores which remain dormant for years until they get a suitable habitat for them to grow, while Archaea do not.
Archaea live in extreme and harsh environments such as salt lakes, oceans,etc. while bacteria are in areas such as in the soil, organic matter, etc.
