The cell membrane is a semi-permeable barrier separating the interior of the cell from the exterior which controls what substances can move in and out of the cell.
The primary physical constituent or the cell membrane is the phospholipid bi-layer. "Floating" within this bi-layer are many different biological macromolecules including proteins and lipids. This description is often referred to as the "fluid-mosaic model."

What else can I help you with?
What is a giant sphere with a light blue membrane that stretches across the entire surface of a cell?
That description fits the cell's plasma membrane, which separates the cell from its external environment and regulates the passage of molecules in and out of the cell.
Does the plasma membrane forms the physical boundary between the cell and its environment?
Yes, the plasma membrane forms the physical boundary between the cell and its environment. It is a selectively permeable barrier that regulates the movement of substances in and out of the cell, maintaining homeostasis. Composed of a lipid bilayer with embedded proteins, the plasma membrane also plays a role in cell signaling and communication with other cells.
What is a description of cell membrane?
It encloses the cytoplasm, and is a protective barrier that controls what goes in and out of the cell.
Do cell membrane contain DNA synthesis?
No, DNA synthesis does not occur in the cell membrane. DNA synthesis occurs in the cell nucleus where the genetic material is contained. The cell membrane primarily functions as a physical barrier that separates the cell's internal environment from the external environment.
What Controls what moves in and out of the cell?
Cell membrane
What is a description of the cell membrane?
The cell membrane lets substances in and out of the cell.
What is the description of endocytosis?
process of taking materials into the cell by means of infolding of the cell membrane
What is a giant sphere with a light blue membrane that stretches across the entire surface of a cell?
That description fits the cell's plasma membrane, which separates the cell from its external environment and regulates the passage of molecules in and out of the cell.
What is a physical description of a cell wall?
it looks like a wall
What is a description of the necleus?
Nucleus in an animal cell is a membrane covered sack which contains the cell's DNA. The DNA is the boss of the cell, and has the directions for forming a new cell.
Does the plasma membrane forms the physical boundary between the cell and its environment?
Yes, the plasma membrane forms the physical boundary between the cell and its environment. It is a selectively permeable barrier that regulates the movement of substances in and out of the cell, maintaining homeostasis.

Which factor prevented the protein molecules from moving out of the cell?
The presence of the cell membrane acts as a physical barrier that prevents protein molecules from moving out of the cell. The cell membrane is selectively permeable, controlling the movement of substances in and out of the cell. Additionally, certain proteins within the cell membrane help to regulate the transport of molecules.
The pinching in of the cell membrane in animal cells is called?
The pinching in of the cell membrane in animal cells is called cytokinesis. This process is part of cell division and involves the physical separation of the two daughter cells.
What Controls what moves in and out of the cell?
Cell membrane
Another name for 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.
