The lipid bilayer makes up the membrane of a cell. The lipid bilayer consists of opposing phospholipids, where the polar ends of both the top layer and the bottom layer of phospholipids face opposite directions.

phospholipids and embedded
The cell membrane is primarily composed of lipids (such as phospholipids) and proteins. These two components work together to control the passage of substances in and out of the cell, maintain cell structure, and facilitate cell communication.
Phospholipids and cholesterol are the two main organic molecules that make up the cell membrane. Phospholipids form a lipid bilayer that provides structural integrity, while cholesterol helps maintain the fluidity and stability of the membrane.
Phospholipids make up the bulk of a cell's membrane. They have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which form a lipid bilayer that provides the structure and integrity of the cell membrane.
Lipids and proteins.
A hydrophilic head and a hydrophobic tail
The cytosol and organelles together make up the cytoplasm of a cell. The cytosol is the gel-like fluid where organelles are suspended and various cellular processes occur. Organelles are membrane-bound structures with specific functions within the cell.
Phospholipids are a major component of the cell membrane.

Nonpolar lipids, specifically phospholipids, make up the majority of the cell membrane. These molecules consist of a hydrophilic (water-attracting) "head" and two hydrophobic (water-repelling) "tails," allowing them to form a bilayer that serves as a barrier to polar substances. This nonpolar nature is crucial for maintaining the integrity and fluidity of the membrane, enabling it to regulate the movement of substances in and out of the cell.
The cell membrane makes the boundary of the cell. It is a lipid bilayer.
