Correct Answer: C) Presence of cell wall made of chitins, mucopolysaccharides and absence of cell organelles like mitochondria and chloroplasts
Solution :
In prokaryotes, Membrane bound cell organelles like Mitochondria, Golgi apparatus, plastids, lysosomes, etc. are absent.
Prokaryotes are basically unicellular.
Cell Wall is absent in some (e.g., Mycoplasma) and present in others (e.g., cyanobacteria).
