Question

The double membrane structure of a cell are

• A. Nucleus
• B. Chloroplast
• C. Mitochondria
• D. All of the above

Answer 1

The correct option is D All of the above

The nucleus is the double membrane bound organelle of eukaryotic cells that serve to house genetic material. The two membranes together make the nuclear envelope. The mitochondrion is double membrane bound organelle wherein the inner membrane is present as infolding and forms cristae. Cristae have respiratory enzymes and serve as the site for cellular respiration. The chloroplast is double membrane-bound organelle in which the inner membrane surrounds the alkaline stroma and thylakoid system. So, the correct answer is option D.
