The cell membrane, or plasma membrane, regulates the passage of materials into and out of cells through selective permeability. This means that only certain substances are allowed to pass through the membrane, while others are blocked or actively transported. This selective permeability helps maintain the internal environment of the cell and allows for proper function and communication with the external environment.

What structure controls the movement of materials into and out of all cells?
The cell membrane, also known as the plasma membrane, controls the movement of materials into and out of all cells. It is a selectively permeable barrier that regulates the passage of substances in and out of the cell to maintain internal homeostasis.
Which structure regulates passage of molecules into and out of cells?
The cell membrane, also known as the plasma membrane, regulates the passage of molecules into and out of cells. It acts as a selectively permeable barrier, allowing some substances to pass through while blocking others to maintain the cell's internal environment.
What is the boundary surrounding all cells?
The cell membrane is the boundary surrounding all cells. It is a selectively permeable barrier that regulates the passage of molecules in and out of the cell.
What type of protective covering do all cells have?
All cells have a protective covering called the cell membrane, also known as the plasma membrane. It surrounds the cell and regulates the passage of substances in and out of the cell.
Which structure is in both plant cells and animal cells controls the passage of substances into and out of cells?
The cell membrane is the structure found in both plant and animal cells that controls the passage of substances into and out of cells. It is a selectively permeable barrier that regulates the movement of molecules such as nutrients, ions, and waste products.
What regulates a passage of materials between the cell and its environment?
cell membrane aka plasma membrane

What function of the cell membrane in all cells?
Maintains the shape of the cell and regulates the passage of what substances go in and out of the cell
What is the body system that regulates the passage of oxygen and nutrients to the cells and takes waste from them?
AnswerThe circulatory system. No iTz Respiratory Sytem
What is the medical term meaning circular muscle found in tubular structures that regulates the passage of substance?
The medical term for circular muscle found in tubular structures that regulates the passage of substances is "sphincter." Sphincters act as valves to control the flow of fluids or materials through tubular structures in the body.
Do cells have a nucleus and a cell membrane?
Yes, cells can have a nucleus and a cell membrane. The nucleus contains the genetic material of the cell, while the cell membrane surrounds the cell and regulates the passage of materials in and out of the cell.
What is the boundary surrounding all cells?
The cell membrane is the boundary surrounding all cells. It is a selectively permeable barrier that regulates the passage of molecules in and out of the cell.
What are the jobs of the plasma membrane?
The plasma membrane regulates the passage of substances in and out of the cell, provides structural support, and plays a key role in cell signaling and communication with other cells.
What type of protective covering do all cells have?
All cells have a protective covering called the cell membrane, also known as the plasma membrane. It surrounds the cell and regulates the passage of substances in and out of the cell.
Do prokaryotic cells have cell membranes?
Yes, prokaryotic cells have cell membranes. The cell membrane surrounds the entire cell and separates its internal environment from the external environment. It regulates the passage of substances in and out of the cell.
Does animal cells generally a cell wall to enclose the cell?
No, animal cells do not have a cell wall. Instead, they are surrounded by a plasma membrane that regulates the passage of substances in and out of the cell.
