It would be the walls of the school or the fence around it.
A school principal can be compared to a cell membrane because they control what comes in and out of the school, just as the cell membrane regulates what enters and exits a cell. They also help maintain a safe and organized environment, similar to how the cell membrane maintains internal stability and protects the cell.
The cell membrane of a car would be like the car's exterior body panels. It provides structure and protection, regulating what enters and exits the cell/car. It also helps maintain internal balance and integrity.
It's the plasma membrane. This is because it acts like a gate regulating what can enter and leave the cell. If the plasma membrane did not exist the cell would die because it might take in something that could kill it.
The cell membrane in a school analogy can be compared to the school's security system, controlling what enters and exits the school to maintain a safe and regulated environment. Just like how the cell membrane regulates the passage of molecules in and out of the cell to maintain cellular balance and function.
cell membrain: school doors, regulates traffic inside and out the school cell Wall: the school walls, protects the school cytoplasm: the air in the school that allows people to be there vacuole: closets of the school, stores stuff
Another name for the cell membrane is the plasma membrane. It is a semi-permeable membrane that surrounds the cytoplasm of a cell, providing structure and regulating the movement of substances in and out of the cell.
It's impossible.
You can compare it to aplane like this a nucelous would be the center of everything like the command center or piolits the mitochandria would be the engine because it gives the plane power the flagella would be the motors because it moves the plane the cytoplasm would be the floor of the plane the cell wall would be the outer of the plane and so on
cell membrane is a jelly like substance surrounding the cell
The cell membrane can be compared to a fence around a house. Just as a fence regulates what enters and exits the property, the cell membrane controls what substances come in and out of the cell. Additionally, like a fence, the cell membrane provides protection and support for the cell.
The purpose of the cell membrane is to let materials like nutrients in and materials like waste out of the cell. They act as doors for the cell.
When looking at a cell as a factory, the cell membrane is like the factory outer walls.
