Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which cells that do not have a true nucleus?
A
animal
B
prokaryotes
C
eukaryotes
D
fungus
Explanation: 

Detailed explanation-1: -A prokaryotic cell doesn’t have a nuclear membrane around the nucleus. The nucleus without a nuclear membrane is called the naked nucleus and it is not considered as a true nucleus. So prokaryotic cells don’t have a true nucleus.

Detailed explanation-2: -Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles.

Detailed explanation-3: -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-4: -A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle.

Detailed explanation-5: -Hint: Prokaryotes are organisms that lack the true nucleus because they do not contain an envelope surrounding the nuclear membrane. Complete answer: The nuclear material of prokaryotes is not bound by a nuclear membrane.
