Vedclass · Answer

(D) Prokaryotic cells are characterized by the absence of a well-defined nucleus (nuclear membrane) and membrane-bound organelles such as mitochondria and chloroplasts.However,all living cells,including prokaryotes,possess a cell membrane (plasma membrane) which acts as a selective barrier.Therefore,the absence of a cell membrane is not a feature of prokaryotes; rather,they are identified by the presence of a cell membrane.
