Inner membrane is convoluted with infoldings

Mitochondrial matrix contains single circular DNA molecule and ribosomes

Outer membrane is permeable to monomers of carbohydrates, fats and proteins

Enzymes of electron transport are embedded in outer membrane

Lysosomes are membrane bound structures.

Lysosomes are formed by the process of packaging in the endoplasmic reticulum.
