Which of the following kingdoms contains prokaryotes?
a. protista
b. eubacteria
c. plantae
d. fungi

Eubacteria is the kingdom that contains prokaryotes  

Further Explanation 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. Kingdom Eubacteria Kingdom Eubacteria is a kingdom that is composed of true bacteria.  

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. Eukaryotes   These are organisms that contain membrane bound nucleus and membrane bound organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, etc. Prokaryotes   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. Similarities between Archaea and Eubacteria Both are prokaryotic organisms   They have ribosomes which is the site for protein synthesis   Both lack membrane-bound cellular organelles such as mitochondrion. Both archaea and bacteria have flagella Differences between Archaea and Eubacteria 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.
