Bacteria. The Bacteria are considered as unicellular prokaryotic organisms. Unlike eukaryotes, bacteria cells lack an organized nucleus, mitochondria, chloroplasts and other membrane bounded organelles. Bacterial cell has only a circular DNA, which does not associate with histone protein.Bacteria do not show sexual reproduction methods.nlike eukaryotes, bacteria cells lack an organized nucleus, mitochondria, chloroplasts and other membrane bounded organelles.

You've already chosen the best response. 2. KINGDOM ARCHAEBACTERIA: They are unicellular prokaryotes with distinctive cell membranes as well as biochemical and genetic properties that differ from all other kinds of life. Many Archaebacteria live in harsh environments. KINGDOM EUBACTERIA: They are unicellular prokaryotes.Most of the bacteria (Germs) that affect your life are members of the Kingdom Eubacteria. KINGDOM PROTISTA: These organisms are placed here more because of what they are not than what they are.Kingdom Protista contains all Eukaryotes that are NOT Plants, Animal, or Fungi, more than 50,000 species in all. Kingdom Protista includes unicellular and a few simple multicellular Eukaryotes.ukaroyotic cells have nuclei and organelles that are surrounded by membranes. The cells of multicellular protists are not specialized to perform specific functions in the organisms. KINGDOM FUNGI: Fungi are Eukaryotes, and most are multicellular. The cells of fungi have cell walls that contain a material called chitin.
