Explanation
A Prokaryotic Cell lacks "Nucleolus". Prokaryotic cells are unicellular organisms that lack a true nucleus and other membrane-bound organelles. The genetic material of prokaryotic cells is typically a single circular molecule of DNA, located in the cytoplasm.
While prokaryotic cells have a cell wall and cell membrane, as well as cytoplasm that contains ribosomes and other cellular components, they do not have a nucleus with a well-defined nuclear envelope, nor do they have nucleoli. In eukaryotic cells, nucleoli are regions within the nucleus where ribosomal RNA (rRNA) is synthesized and ribosomes are assembled. This process is absent in prokaryotic cells, as they lack a nucleus and have a different mechanism for synthesizing proteins.
