Golgi body
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.

A system of parallel flattened membrane-bounded sacs called cisternae. Continuous with the outer membrane of the nuclear envelope. Act as an intracellular transport system.

Vacuole Membrane-bound sacs are said to receive and package proteins
These membrane bound sacs are called vesicles.

Membrane-bound spaces are sacs surrounded by a membrane that are known as vesicles. Vesicles are involved in various cellular processes, including transporting molecules within the cell, and interacting with other organelles.
The Golgi complex packs proteins and other materials into membrane-bound sacs called vesicles. These vesicles transport the molecules to their final destinations within the cell or outside of the cell.
Membrane-bound sacs that are filled with fluid.
The endoplasmic reticulum is the organelle that's looks like a stack of sacs.
