Detailed explanation-1: -Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. The absence of a nucleus and other membrane-bound organelles differentiates prokaryotes from another class of organisms called eukaryotes.

Detailed explanation-2: -Reason: The cells that lack membrane bound organelles are called prokaryotic.

Detailed explanation-3: -The smallest cell organelle without cell membrane is ribosome.

Detailed explanation-4: -The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Detailed explanation-5: -Complete answer: Option A: Prokaryotic cells are the most primitive cell type which lacks any membrane bound internal structures. So, membrane bound organelles are absent in prokaryotes. This is the correct option.
