Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cells that do not have a true nucleus are called ____
A
eukaryote
B
prokaryote
C
unicellular
D
multicellular
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 bacteria which lack membrane-bound organelles and nucleus. Eukaryotes have a well defined nucleus.

Detailed explanation-3: -Eukaryotes (meaning ‘true nuclei” where “karyote” is derived from the ancient Greek for “kernel") include fungi, protozoa, eukaryotic algae, and of course plants and animals including ourselves. Eukaryotic cells have a nucleus containing chromosomal DNA bounded by membranes.

Detailed explanation-4: -Prokaryotic cells do not have a nucleus. All cells can are classified as prokaryotic or eukaryotic based on their internal structure. Eukaryotic cells contain a nucleus-a structure enclosed in a membrane that contains the majority of the cell’s genetic material. Prokaryotic cells lack nuclei.
