Detailed explanation-1: -Answer and Explanation: Option e) endoplasmic reticulum is the correct answer. The endoplasmic reticulum is called a membrane-bound organelle of which prokaryotic cells lack membrane-bound organelles. The cell wall, plasma membrane, and ribosomes can be found in prokaryotes but endoplasmic reticulum is absent.

Detailed explanation-2: -Prokaryotes do not possess a rough ER. The endoplasmic reticulum and other membrane-bound organelles are absent in prokaryotes.

Detailed explanation-3: -Endoplasmic reticulum, microtubules, and the Golgi apparatus are unique to eukaryotic cells, and will not be found in prokaryotes. Prokaryotes do, however, contain ribosomes, though smaller than the ribosomes in eukaryotic cells.

Detailed explanation-4: -All prokaryotes have plasma membranes, cytoplasm, ribosomes, a cell wall, DNA, and lack membrane-bound organelles.

Detailed explanation-5: -Hence, the correct answer is ‘Production of ribosomes’.
