|
A relatively permeable smooth outer membrane only.
|
|
|
A roughly folded outer membrane with high permeability to small molecules and smooth inner membrane.
|
|
|
A smooth outer membrane and folded inner membrane.

Detailed explanation-1: -Mitochondrion possesses double membrane as its covering. The outer smooth surface and the inner membrane forms infoldings called as cristae, which increases surface area for more formation of energy in the form of ATP.
Detailed explanation-2: -An exterior membrane and an inner membrane make up the double membrane-bound structure known as the mitochondria. The membrane’s outside is largely smooth. Cristae, or extremely convoluted folds, are formed in the inner membrane. The surface area of the inner membrane is considerably increased by the cristae.
Detailed explanation-3: -The inner membrane of the mitochondrion folds inwards, forming the cristae. This folding allows a greater amount of membrane to be packed into the mitochondrion.
Detailed explanation-4: -The outer membrane is smooth and forms the continuous limited boundary of the mitochondria. The inner membrane forms a number of infoldings in mitochondria. These infoldings are known as cristae.
