No, all cytoplasmic compartments are formed from the 'pinching off of folded membrane segments'.
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.

Phospholipids form the lipid bilayer that are the basis of cell membranes.
A double layer of phospholipids makes up most of your cell membranes

The organelle that contains a smooth outer membrane and a folded inner membrane in a cell is the mitochondrion. Mitochondria are responsible for producing energy in the form of ATP through a process called cellular respiration.

Nuclear membranes start to form during cell division in the late stages of mitosis, specifically during telophase.

Protect the cell form any disease or harmful bacteria.
Only a plant has a cell wall. Animals have cell membranes.
The main component of cell membranes is phospholipids - which form a bilayer (with polar heads facing outwards and tails facing inwards).
