The plasma membrane.
Carrier proteins and ion channels are parts of the plasma membrane, and aid in diffusion across concentration gradients, as most things don't freely move from one end of the cell membrane to the other.
The Sodium-Potassium pump is a major ion channel in the plasma membrane, and regulates the intake of potassium and export of sodium (3 molecules sodium out, 2 molecules potassium in.)
What else can I help you with?
One of the most important functions of the cell membrane is to?
control what substances enter and exit the cell. It acts as a barrier, allowing only certain molecules to pass through via various transport proteins. This selective permeability helps maintain the cell's internal environment and carry out essential cellular processes.
What maintains a chemical balance within a cell by regulating the materials that enter and leave the cell?
The cell membrane, specifically through the process of selective permeability, helps to maintain a chemical balance within a cell by controlling the substances that can enter and exit the cell. This regulation ensures that essential molecules are able to enter the cell while harmful substances are kept out, contributing to the overall health and function of the cell.
The part of the cell that regulates what can enter and leave?
The cell membrane determines what comes in and what goes out. Water goes in and out by osmosis which is a passive method. Others require the help of proteins that act as doorways. These require energy and the method is called active transportation.
What cell main job is to control which substances enter and leave a plant cell.?
The cell organelle responsible for controlling which substances enter and leave a plant cell is the cell membrane, specifically the plasma membrane. The plasma membrane is a selectively permeable barrier composed of phospholipids and proteins that regulate the passage of molecules such as nutrients, water, and waste products. Through processes like diffusion, osmosis, and active transport, the plasma membrane maintains cellular homeostasis by allowing essential substances to enter the cell while preventing harmful substances from entering.
What is the function of a cells selectively permeable membrane?
Regulates what enters and leaves the cell
The nuclear envelope regulates which substances enter and leave a cell?
False
What is the function of the cell membrane in a plant cell called?
The cell membrane protects the cell and regulates what substances enter and leave the cell.

What structure of the cell regulates what material leave or enter the cell?
This is the function of the Golgi Body.
What regulates what can enter and leave the cell?
The cell membrane
What is the function of the cell selectively permeable plasma membrane?
it regulates what materials enter and leave the cell
What is the function of a cell selectively permeable plasma membrane?
it regulates what materials enter and leave the cell
What acts as a barrier and decides which substances can enter and leave the cell?
The cell membrane.
Through which organelle do substances enter or leave a cell?
Substances pass through the plasma membrane, although ot is not technically an organelle.
What substances enter and leave the cells?
Proteins made on "bound" (attached) ribosomes leave through the cell membrane, and other proteins will enter the cell.
