Vedclass · Answer

(A) Prokaryotic organisms (such as bacteria) are characterized by the absence of a well-defined nucleus and membrane-bound organelles. Their genetic material is typically present as a naked circular $DNA$ molecule known as the nucleoid. They possess a rigid cell wall (except in Mycoplasma) that provides structural support. Option $A$ is correct because prokaryotes lack a true nucleus and possess a rigid cell wall. Option $B$ is incorrect as their cell wall is made of peptidoglycan,not cellulose. Option $C$ is incorrect as it describes a eukaryotic cell. Option $D$ is incorrect because many prokaryotes are heterotrophic.
