Detailed explanation-1: -Plant chloroplasts are large organelles (5 to 10 m long) that, like mitochondria, are bounded by a double membrane called the chloroplast envelope (Figure 10.13).

Detailed explanation-2: -Structure of a mitochondrion. Mitochondria are bounded by a double-membrane system, consisting of inner and outer membranes. Folds of the inner membrane (cristae) extend into the matrix.

Detailed explanation-3: -Double membrane-bound organelles: Nucleus, mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.
