1. The cell membrane separates the cell from its surroundings, acting as a barrier between the inside of a cell and the cell's environment, but, in plants, fungi and some bacteria, there is a cell wall that surrounds the cell membrane
2. It holds the cell contents and protects it from changes in the chemical and physical environment.
3. It acts as a partially permeable membrane to control the movements of substances in and out of the cell by processes such as diffusion, osmosis, and active transport. Some pass through passively through protein channels, whereas others need to be actively brought from one side to the other with protein carrier molecules.
Most membranes consist of a double layer of a fatty substance called phospholipid. Proteins occur at various points and extend to different depths within the double layer of phospholipids. Only needed materials can enter the cell and its parts because of the structure and chemical composition of the membranes.

What is the function of the cell membrane and the plasma membrane?
Cell membrane is also known as plasma membrane. Controls exchange of materials such as nutrients and waste between cells and their environment. Has other important functions for example to enable cells to receive hormones.
How are the properties of phospholipids important in membrane functions?
Phospholipids are really just fat cells that exist in our membranes. They serve two very important functions. The most important are they help with temperature control. When the membrane gets cold, the phospholipids keep the membrane from freezing and becoming stiff, and when it gets too hot, they keep the cells form sticking together and melting
What are the cytoplasmic space in eukaryotic cells is occupied by many diverse membrane-bound structures with specific cellular functions?
Organelles
What molecule carries chemical energy the cells use for their functions?
This molecule is ATP (Adenosine Triphosphate), a nucleoside.
What is the three functions of a nuclear membrane in cells?
The nuclear membrane insures that the interior of the nucleus is isolated from a cell's cytoplasm, allowing two different environments to be maintained.- Glad to help you out =]
What is a cell membrane and what are the functions of a cell membrane?
They help control what enters and leaves the cells.
Infer the functions of the cell membrane All cells have a cell membrane where do you think the cell membrane of a plant cell located?
the cell membrane is the outer part of the cell wall.
What is the function of the cell membrane and the plasma membrane?
Cell membrane is also known as plasma membrane. Controls exchange of materials such as nutrients and waste between cells and their environment. Has other important functions for example to enable cells to receive hormones.
What are the functions of cell membrane in all cells?
the cell membrane is like the skin of a cell. it keeps everything in that needs to be in and everything out that needs to be out.
Where is the cell membrane located in the cells that do not have cell walls?
Animal cells are the type of cells that do not have cell walls. The location varies depending on where the cell functions.
How are cells adapted to its functions?
They have adapted to their job by developing a cell membrane to keep unwanted waste
What function of the cell membrane is in every cell?
It is for maintaining liquids in a cell which is necessary for al the cells functions
What does the cell membrane do in plant and animal cells?
They protect and hold the cells together. It controles wht goes in and out of the cell.
What two primary functions do lipids perform in cells of a multicellular animal?
From what i know they are used in the cccell membrane and for hormones
What are all the functions of a cell membrane in all cells?
Due to its semi permability a cell membrane controls what goes in and out of the cell..in simplicity it determines what is right to enter the cell.
How are the properties of phospholipids important in membrane functions?
Phospholipids are really just fat cells that exist in our membranes. They serve two very important functions. The most important are they help with temperature control. When the membrane gets cold, the phospholipids keep the membrane from freezing and becoming stiff, and when it gets too hot, they keep the cells form sticking together and melting
What substance crossed the dialysis membrane?
Cells have methods other than diffusion/osmosis to move materials across the cell membrane, most of which involve membrane proteins and require the use of energy. The cell membrane also performs functions other than controlling the movement of materials into and out of the cell, and the membranes of some specialized cells have very complex functions. So we can see that the cell membrane is a very intricate and important component of the cell.
