If you include the plasma membrane, then it's
Cell membrane is composed of lipid bilayer.
The major component of the cell membrane is phospholipids. They form a lipid bilayer that acts as a barrier to control the passage of molecules in and out of the cell. Proteins embedded in this lipid bilayer also play key roles in cell membrane function.
The organelle that controls what goes in and out of a cell is the plasma membrane, also known as the cell membrane. It is a selectively permeable barrier made primarily of a lipid bilayer, proteins, and carbohydrates. This structure allows the cell to maintain homeostasis by regulating the movement of substances, such as nutrients and waste products.
The endoplasmic reticulum (ER) is the organelle responsible for assembling some components of the cell membrane and synthesizing lipids. The rough ER, studded with ribosomes, is involved in protein synthesis, while the smooth ER plays a crucial role in lipid synthesis and metabolism. Together, they contribute to the production and modification of membrane proteins and lipids, essential for maintaining the cell's structural integrity and functionality.
Ribosome is a cell organelle not bounded by membrane. It is responsible for protein synthesis in the cell.

The endoplasmic reticulum
The endoplasmic reticulum is the cell organelle responsible for membrane and lipid synthesis as well as detoxification. The smooth endoplasmic reticulum, in particular, plays a role in these functions due to its lack of ribosomes and its specialization in lipid metabolism and detoxification processes.
The endoplasmic reticulum is an internal membrane system where lipid components of the cell membrane are assembled, along with proteins and other materials. It is involved in protein synthesis, modification, and transportation within the cell.
Another lipid found in the cell membrane is cholesterol.
Both the cell membrane and the nuclear membrane are lipid bilayers that separate the internal environment from the external environment. They both regulate the transport of molecules in and out of the cell/organelle, and help maintain the overall structure and function of the cell/organelle.

They are of two types. The components that assemble to form the Cell [bi-lipid-layer] membrane are called fatty-acids, and the mostly proteinaceous Adjuncts,/ Ancillary Components are known as Cell Membrane Control Factors.
The cell membrane is a lipid bilayer while the organelle membranes are usually a single layer of lipids. The nucleus, mitochondria and chloroplasts are the exception and have a lipid bilayer. AS you see, it depends on which organelle. The nucleus, mitochondria and chloroplasts have a bilayer (2). The others have one.
An organelle is a specialized subunit within a cell that performs a specific function and is enclosed within its own lipid membrane. Examples of organelles include the nucleus, mitochondria, and chloroplasts. Each organelle contributes to the overall functioning of the cell by carrying out specific tasks.
