A cell contains naked circular genomic DNA, 70S ribosomes, inclusion bodies and pigment-containing membranous extensions
Naked circular genomic DNA, 70S ribosomes, inclusion bodies and absence of membrane-bound organelles identify a prokaryotic cell. Pigment-containing membranous extensions are chromatophores found in some prokaryotes such as cyanobacteria.
