It has selective permeability (allows it to control what comes in and out of the cell) and it isolates the cytoplasm.
The plasma membrane specializes in controlling the movement of substances in and out of the cell through selective permeability. It also plays a role in cell communication and recognition through protein receptors embedded in the membrane. Additionally, the plasma membrane helps maintain the cell's shape and structure.
Fatty acids in the plasma membrane help provide structure and flexibility to the membrane. They also play a role in cell signaling and transport processes by interacting with membrane proteins and influencing their activity. Additionally, they can affect the fluidity and permeability of the membrane.

The organelle responsible for renewing and modifying the plasma membrane is the Golgi apparatus. It processes, sorts, and packages lipids and proteins for transport to the plasma membrane, where they can be incorporated into its structure. Additionally, the Golgi apparatus plays a crucial role in glycosylation and other modifications that affect membrane composition and function.
The plasma membrane consists mainly of lipids (phospholipids, cholesterol), proteins (integral and peripheral), and carbohydrates (glycoproteins, glycolipids). These components work together to maintain the structure and function of the membrane, allowing it to regulate the flow of molecules in and out of the cell.
Structure and function
Increased cholesterol in the plasma membrane can lead to a more rigid and less fluid membrane structure. This can affect the membrane's ability to allow substances to pass through and communicate with other cells, potentially impacting overall cell function.
An increase in cholesterol in the plasma membrane can make the membrane more rigid and less fluid. This can affect the membrane's ability to allow substances to pass through and communicate with other cells. Overall, it may impact the membrane's structure and function by altering its flexibility and permeability.
Cholesterol is a type of lipid that helps maintain the fluidity and stability of the plasma membrane. It is embedded within the phospholipid bilayer, where it regulates the membrane's flexibility and permeability to substances. Cholesterol also plays a role in organizing and maintaining the structure of the membrane, which is essential for proper cell function.
The thin living membrane surrounding the cytoplasm is called the cell membrane or plasma membrane. It acts as a barrier that controls the passage of substances in and out of the cell, helping to maintain cell structure and function.

Additionally, they can affect the fluidity and permeability of the membrane.
The cell membrane consists of a lipid bilayer which is actually a phospholipid. Cell membranes are semipermiable and they regulate what enters and leaves the cell.
plasma membrane
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
