GENERAL HISTOLOGY

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: -The monerans are considered to be the most primitive organisms. These are unicellular prokaryotes that do not have a well-defined nucleus (without a nuclear membrane) and other membrane-bound organelles. So, the correct answer is monerans.

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.

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: -The prokaryotic cell’s genetic material is located in an area with an irregular form called a nucleoid, which is a nucleus-like structure. Prokaryotic cells lack a true nucleus. The nucleus is devoid of the nuclear membrane.
