The plasma membrane's function is that it allows substances to enter or leave the cell. Its importance is that it acts as a boundary, holding the cell constituents together and keeping other substances from entering. It is found underlying the cell membrane in the cytoplasm and provides a scaffolding for membrane proteins to anchor to.
--------------------------
The plasma or cell membrane is made up of a double layer of phospolipid molicules with holes through it made from proteins.

What else can I help you with?
Are peripheral steroids part of plasma membrane?
No, peripheral steroids are not part of the plasma membrane. Peripheral steroids are molecules found in the cytoplasm and do not directly interact with the plasma membrane. The plasma membrane is primarily composed of phospholipids, proteins, and cholesterol.
Where is cholesterol found in cell membrane?
The plasma membrane is present in all prokaryotic and eukaryotic cells. It is the semi-permeable membrane that encloses the cell. So to clearly answer your question, the plasma membrane is found on the outside of the cell; it encircles the cell.
Is a plasma membrane composed of Cholesterol molecules?
Yes, the plasma membrane is composed of a phospholipid bilayer with proteins embedded in it. Cholesterol molecules are also present in the plasma membrane, helping to regulate its fluidity and stability.
Example of Plasma membrane found inside the body?
A specific example of a plasma membrane found inside the body is the cell membrane, which surrounds all cells and acts as a barrier to regulate the passage of molecules in and out of the cell. It is composed of a phospholipid bilayer embedded with proteins that help facilitate various cellular functions.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
Are peripheral steroids part of plasma membrane?
No, peripheral steroids are not part of the plasma membrane. Peripheral steroids are molecules found in the cytoplasm and do not directly interact with the plasma membrane. The plasma membrane is primarily composed of phospholipids, proteins, and cholesterol.
Can large polar molecules pass through the plasma membrane?
No, large polar molecules cannot pass through the plasma membrane.

What Molecules in the plasma membrane function as transporters?
Proteins
What are most of the molecules that compose the plasma membrane?
phospholipids
Are plasma membrane found in plant cells?
Of course they are found in plant cells.Every living cell has a plasma membrane.
Do plant cell's animal cell's and bacterial cell's all have a plasma membrane?
Yes, all plant cells, animal cells, and bacterial cells have a plasma membrane. The plasma membrane is a semi-permeable membrane that surrounds the cell and regulates the passage of molecules in and out of the cell.
What are the molecules in the plasma membrane made of?
phospholipids are the molecules that make up the plasma membrane and they are made of polar (hydrophilic) heads and 2 non-polar (hydrophobic) tails
Which type of molecule is found in the plasma membrane?
The plasma membrane is composed mostly of phospholipids
What type of molecules embebbed in the plasma membrane allows molecules to pass through the membrane by active or passive transport?
proteins
