Detailed explanation-1: -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-2: -Prokaryotic cells lack a nucleus and membrane-bound structures. Eukaryotic cells have a nucleus and membrane-bound structures called organelles.

Detailed explanation-3: -The most straight-forward answer would be that they do not need one. This article suggests that the evolution of the nuclear membrane allowed the separation of the processes of translation from transcription. This allowed greater control of these two key cell functions.

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.

Detailed explanation-5: -Final answer: Red blood cells do not possess a nucleus.
