Explanation

Correct answer. The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells Ribosomes are small, electron-dense particles not enclosed in membrane and are located in the cytosol. Ribosomes are involved in protein synthesis. Inclusion bodies are the transitory residents of the cytoplasm not involved in cell metabolism and do not survive cell division. They comprise mainly accumulated metabolites, lipid droplets and pigments and are sporadically distributed in body cells. An endospore is dormant, tough, and non-reproductive structures produced by certain bacteria from the Firmicute phylum, that help bacteria survive in adverse conditions.
