Solution
The correct option is C Nuclear membrane and membranous cell organelles
Prokaryotic cells are characterized by the absence of a membrane-bound true nucleus and other membrane-bound organelles such as mitochondria, Golgi apparatus, E.R. etc. Their DNA fibrils are present in the center of the cell, i.e., in the nucleoid. It consists ribosomes which are the site of protein synthesis and have two subunits; large and small. Prokaryotic ribosomes have 30S and 50S subunits that together make a 70S ribosome. Thus, the correct answer is option C.
