or also a front door cause it regulates what enters the room and what leaves it
Its called "the fluid mosaic model" of the cell membrane. This describes the clumping together of phospholipids to form rafts and their motion (along with single phospholipids) throughout the 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.
the cell membrane is as flexible barrier outside of the cell.

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
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.
I suppose you could compare the mantle to the cell wall or cell membrane.
the nucleus
It would be the walls of the school or the fence around it.
A cell membrane can be compared to a barrier or protective fence. It regulates the passage of materials in and out of the cell, just like a gatekeeper controls who enters and exits a space. Additionally, it is flexible and dynamically adjusts its shape, much like a stretchy security net.
Cell membrane allows entry of selected particles and not other macromolecules. Similarly, walls of a school will not allow a person who fails to give his or her identity to enter. Cell membrane, however, has water proofing property. Cell membrane also have specialized proteins in it.
One of the ways that a cell compares to a school is that the nucleus is like the principal.
Just as a school building controls what enters and exits the premises, the cell membrane encloses the cell and regulates the passage of substances in and out. Both act as a barrier providing protection and maintaining internal conditions.
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.
Its called "the fluid mosaic model" of the cell membrane. This describes the clumping together of phospholipids to form rafts and their motion (along with single phospholipids) throughout the membrane.
Many textbooks will compare a cell membrane to the fluid mosaic model, which means that the parts of the membrane (phospholipids, cholesterol, proteins etc.) are not stuck in one place; they move around and can pass by one another while still keeping the integrity of the membrane. That is mainly for the structure, but structure always lends to function.
