Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bacteria are ____
A
Unicellular eukaryotes
B
Multicellular eukaryotes
C
Unicellular prokaryotes
D
Multicellular prokaryotes
Explanation: 

Detailed explanation-1: -Bacteria and archaea are all unicellular prokaryotes. Eukaryotes do have cell nuclei and their structures are more complex. Yeasts and algae are examples of unicellular eukaryotes. Unlike prokaryote cells, eukaryote cells have organelles, cell organs fulfilling important functions in the cell.

Detailed explanation-2: -While prokaryotes are always unicellular organisms, eukaryotes can be either unicellular or multicellular.

Detailed explanation-3: -Bacteria are not multicellular. They are unicellular organisms, possessing only one cell. All functions required to sustain life like growth, metabolism, reproduction, etc are carried out by a single cell in bacteria.

Detailed explanation-4: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.

Detailed explanation-5: -Prokaryotes are simple organisms that lack membrane-bound organelles. All prokaryotes are unicellular. They consist of only one cell. Example: bacteria. They possess a ‘nucleoid’ instead of a true nucleus.
