Prokaryotes lack membrane bound organelles like nucleus, mitochondria and chloroplast. Prokaryotic cells are unicellular organisms, which reproduce through binary fission. In some cases, few prokaryotic organisms also reproduce by budding. Prokaryotic cells have a cell envelope, which generally consists of a capsule, cell wall (chitin and mucopolysaccharides), cytoplasm, plasma membrane, cytoplasm region or nucleoid region, ribosome, plasmids, pili and flagella. They are autotrophs, phototrophs, chemotrophs and heterotrophs.
Thus, the correct answer is option (C).
