Detailed explanation-1: -Cells are of two types based on cellular structure, i.e., prokaryotes and eukaryotes . Prokaryotes have an undefined nuclear area whereas eukaryotes have a well-defined nucleus.

Detailed explanation-2: -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-3: -Explanation: Prokaryotic cells differ from eukaryotic cells in that they lack any membrane-bound organelles, including a nucleus. Instead, prokaryotic cells simply have an outer plasma membrane, DNA nucleoid structure, and ribosomes.

Detailed explanation-4: -There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes-organisms composed of a prokaryotic cell-are always single-celled (unicellular). Prokaryotic cells don’t contain a nucleus.

Detailed explanation-5: -On the basis of nature of nucleus organisms are classified into two main groups. They are, Prokaryotes (genetic material without nuclear membrane). Eukaryotes (genetic material surrounded by nuclear membrane).
