Detailed explanation-1: -Mitochondria, plastids and nucleus are double membrane-bound organelles of the cell.

Detailed explanation-2: -Mitochondria are double-membrane-bound structures. The membrane of a mitochondrion is divided into the inner and outer membranes, distinctly divided into two aqueous compartments – outer and inner compartments. The outer membrane is very porous (containing the organelle), while the inner membrane is deeply-folded.

Detailed explanation-3: -Nucleus. The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control centre of the cellular activities and is the storehouse of the cell’s DNA.

Detailed explanation-4: -The double membrane-bound organelles are mitochondria, chloroplasts and the nucleus.
