The folds (cristae) make for a larger surface on which chemical reactions can take place and hence improve productivity of the mitochondria.

Folded membranes in cells are more effective because they have more surface area. The wider area of space allows for more activity to occur without damage to the cell because of membrane's resistance.
The mitochondria are surrounded by two membranes, the outer is smooth & the inner is folded into critae which increase the surface area. :)

They don't, they have sacs called thylakoids that are layered to form a granum. You're probably talking about mitochondria, which has a folded inner membrane. The membranes are folded here for increased surface area. This then allows for more ATP to be produced.
No, all cytoplasmic compartments are formed from the 'pinching off of folded membrane segments'.
