The cell membrane is composed of the lipid bilayer. In addition to lipids most membranes contain proteins and carbohydrates.

ReneA cell membrane is primarily composed of phospholipids, proteins, and cholesterol. Phospholipids form a bilayer that acts as a barrier, while proteins are embedded within the membrane and have various functions such as transport and signaling. Cholesterol helps maintain the fluidity and stability of the membrane.

What organelle is composed of a phospholipid bilayer?
The organelle that is composed of a phospholipid bilayer is the cell membrane. It surrounds the cell and acts as a barrier, controlling what substances can enter and leave the cell.
What are cell membranes and cell wall composed of?
Cell membranes are composed primarily of phospholipids and proteins, while cell walls are composed of cellulose in plants, chitin in fungi, and peptidoglycan in bacteria. Both structures provide support and protection for the cell.
Which cell part is a thin membrane that lets materials in and out of a cell?
Referred to as either a cell membrane or a plasma membrane. Is composed of a phospholipid bilayer with embedded protein channels.
What is a monera's cell membrane composed of?
Monera's cell is a prokaryotic cell i.e. it is composed of everything that a eukaryotic cell but without a nucleous.
What is the cell structure that is located in the external boundaries of the cell?
The cell structure that is located in the external boundaries of the cell is the cell membrane. The cell membrane is a semipermeable membrane composed of lipids and proteins that surrounds the cell, providing a barrier between the cell's interior and its external environment.
