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.

The cell membrane is responsible for regulating what can enter and leave the cell. It acts as a barrier that controls the passage of molecules and ions in and out of the cell to maintain internal balance. The cell membrane is selectively permeable, allowing some substances to pass through while blocking others.

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 is the part of a cell where charges enter and exit?

The cell membrane is the part of a cell where charges (ions) enter and exits. It regulates the movement of ions in and out of the cell, maintaining the cell's internal environment and allowing for communication with the external environment.


What part of the cell regulates the entrance and exit of molecules for the cell?

The cell membrane is a busy cell. This cell regulates what can and cannot leave.


What cell main job is to control which substances enter and leave a plant cell.?

The main job of the cell responsible for controlling which substances enter and leave a plant cell is the cell membrane. It acts as a selectively permeable barrier, allowing nutrients and other essential substances into the cell while keeping unwanted substances out. Additionally, the cell membrane also helps maintain the cell's internal environment by regulating the movement of molecules.


Which part of a cell allows certain materials to enter the cell and other material to exit the cell?

The cell membrane, also known as the plasma membrane, regulates the passage of materials in and out of the cell through the process of selective permeability. Transport proteins and channels embedded in the cell membrane control the movement of substances, facilitating the entry of essential nutrients and the removal of waste products.
