Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Bacteria is what type of cell?
A
prokaryote
B
eukaryote
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The cell types in Bacteria and Archaea are considered as “prokaryotes.” The use of the term prokaryote was first introduced as a result of electron microscope studies showing a shared simple cell structure among bacteria (Stanier & Van Niel 1962).

Detailed explanation-2: -The bacteria are the oldest and simplest living organisms, and all of the bacteria are “prokaryotes, ‘’ meaning that they do not have a true membrane-bound nucleus as eukaryotes do.

Detailed explanation-3: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.

Detailed explanation-4: -Prokaryotes are organisms whose cells lack a nucleus and other organelles. Prokaryotes are divided into two distinct groups: the bacteria and the archaea, which scientists believe have unique evolutionary lineages. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.

Detailed explanation-5: -Unicellular organisms can be prokaryotes or eukaryotes. Prokaryotes do not have cell nuclei: their structures are simple. Bacteria and archaea are all unicellular prokaryotes. Eukaryotes do have cell nuclei and their structures are more complex.
