The cell membrane
phospholipids
Mitochondria are the only organelle in a cell which is surrounded by a double layered membrane. Also chloroplast in plants are surrounded by double layered membrane.
60%phospholipids and 30% proteins and10% carbohydrates
All cells are surrounded by a cell membrane - which is mostly a bilayer (double layer) of phospholipids.
The cell membrane is a complicated structure layered rather like a sandwich. The two pieces of bread are the lipid bilayers (bilayers as in the two pieces), the meats and cheeses is the hydrophobic region, and proteins are like the toothpick that is sticking out of the sandwich (there are multiple) and there are various carbohydrate chains coming off of the proteins, like the plastic wrapper on the top of the toothpick.

phospholipid bilayer
Look for the double layered outer perimeter. The one with the double line has a cellular wall and is the plant cell.

Cytoplasm
It is the double-layered membrane surrounding the nucleus of a eukaryotic cell, separating the nucleoplasm from the cytoplasm.

Eukaryotic and prokaryotic cells both have a double layered cell membrane and they both contain DNA.
