The cell membrane consists of two molecular structures: Proteins and Phospholipids. The proteins are used for cell recognition, communication, and for moving substances in and out of the cell. The vast majority of the cell membrane is made of phospholipids. A phospholipid consists of a phosphate "head" with two long "tails" of lipids. The phosphate head is "hydrophilic" meaning it is attracted to liquid environments. The lipid tails are "hydrophilic" meaning they move away from liquid environments. The cell membrane is two layers of these phospholipids. The outer layer has the heads pointing towards the liquid environment outside the cell. The inner layer has the heads pointed inwards towards the liquid interior of the cell. The tails are on the inside of this layer, in a dry environment.

What else can I help you with?
What is a thin layer of fat that surrounds the cell?
The cell membrane is made mostly of lipids (fats) and they have some proteins in them; somewhat like islands in a sea.
How are lipids used in plants?
Plants need lipids/fats to help make up the double layer of the cell membrane.
What is the cell structure made up of a double layer of fat material?
The cell membrane, or phospholipid bylayer.
What is the outer layer of a cell that acts as a gatekeeper to a cell?
The outer layer of a cell that acts as a gatekeeper is called the cell membrane. It regulates the movement of substances in and out of the cell to maintain internal balance.
What is the outer surrounding layer of plant and animal cell?
The outer surrounding layer of a plant cell is the cell wall, which provides structure and support. In an animal cell, the outer layer is the cell membrane, which controls the movement of substances in and out of the cell.
What is made of double layer fats in a cell?
The double layer fats in a cell are known as phospholipids, which make up the cell membrane. This lipid bilayer acts as a barrier that separates the internal environment of the cell from its external surroundings. The phospholipid bilayer also helps regulate the passage of substances in and out of the cell.
How are lipids used in plants?
Plants need lipids/fats to help make up the double layer of the cell membrane.
What is a thin layer of fat that surrounds the cell?
The cell membrane is made mostly of lipids (fats) and they have some proteins in them; somewhat like islands in a sea.
What is the stiff outer layer that surrounds the outer layer of the cell membrane?
cell membrane
The protective layer around all cells is called the?
the cell membrane
Why would fat substances rapidly affect a cell?
The cell membrane is also called a phospholipid bi-layer. In other words, it is like an Oreo cookie, with a layer of lipids on both sides, made of fat, with a layer of phosphorus in the middle. So every cell in your body needs fats in order to form and function properly.
What is the outer layer of a cell?
The outer layer of a cell is the cell membrane or plasma membrane
What is the cell structure made up of a double layer of fat material?
The cell membrane, or phospholipid bylayer.
What is the layer around the Cell called?
The layer around a cell is called a membrane.
What is the cell membrane and what is its function?
The cell membrane is a protective layer that protects the cell inside of it.
What is the cell membrane and what is the function?
The cell membrane is a protective layer that protects the cell inside of it.
Where is a cell membrane found in?
In a plant cell it is located just inside of the cell wall (outer layer). In an animal cell, the cell membrane is the outer layer.
