The cell membrane is primarily composed of lipids such as phospholipids, cholesterol, and glycolipids. These lipids form a lipid bilayer that surrounds the cell, providing structure and regulating the movement of molecules in and out of the cell. Proteins are also embedded in the membrane, serving various functions such as transport, signaling, and structural support.
Water cannot pass through phospholipids because phospholipid molecules have hydrophobic tails that repel water molecules, preventing them from passing through the lipid bilayer.
Phospholipids.
Phospholipids and proteins are the two main types of molecules that make up the cell membrane. Phospholipids form a lipid bilayer that serves as the basic structure of the membrane, while proteins are embedded within this lipid bilayer and help to carry out various functions such as transport, signaling, and support.
Phospholipids are essential components of cell membranes, forming a lipid bilayer that provides structure and acts as a barrier to regulate the movement of molecules in and out of the cell. They also play a role in cell signaling, cell recognition, and membrane fluidity.

There are two layers of phospholipids in the plasma membrane, with each layer composed of phospholipid molecules arranged in a bilayer structure. This bilayer provides the membrane with its characteristic flexibility and semi-permeability.

The fluid bilayer, composed of phospholipids, forms the basic structure of cell membranes. It acts as a barrier to control the movement of substances in and out of the cell, helping to maintain cellular homeostasis. Additionally, the fluidity of the bilayer allows for flexibility and dynamic interactions with proteins and other molecules within the cell membrane.
Phospholipids make up this layer. Phospholipids belong to the family of biological polymers.
Yes, phospholipids are polarized molecules because they contain both a hydrophilic (polar) head and hydrophobic (nonpolar) tails. This dual nature allows them to form the lipid bilayer structure in cell membranes.
