1 Answer
Ans : (a) Lysosomes
Explanation :
Nucleus is the double membrane bound organelle of eukaryotic cells that serve to house genetic material. The two membranes together makes the nuclear envelope.
Mitochondrion is double membrane bound organelle, wherein the inner membrane is present as infolding and forms cristae. Cristae have respiratory enzymes and serve as a site for cellular respiration.
Chloroplast is double membrane bound organelle in which the inner membrane surrounds the alkaline stroma and thylakoid system.
Lysosomes are bound by single layer of typical phospholipids.
