Cellophane is a good analogy. It is a semi-permeable membrane which is permeable to water and small molecules, but not to large molecules, and can be used to demonstrate the principal of osmosis. Cellophane is made out of plant fibers called cellulose but living membranes are made out of layers of fat cells.

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.
The cell membrane acts like a security gate, controlling what enters and exits the cell. It can also be compared to a selective barrier, allowing only specific molecules to pass through. Additionally, it functions like a border patrol, monitoring and regulating the traffic in and out of the cell.
I think it can sometimes be referred to as plasma membrane and in plants they have a cell membrane and a cell wall (don't confuse the two)! Whoever just said that gave you the wrong answer. There is a nuclear membrane, and it's not very easy to get cell and nucleus membrane confused, so i suggest the person who first answered your question go back to second grade, because - sorry to break it to you, but - they're wrong. Please try not to take advice from them, because i can assure you, it will most likely not be valid. Now, what kind of analogy do you need? A city analogy? A country analogy? Whatever it is, let me know, and maybe i can find it for you. :)
A cell membrane is like a flexible plastic window with tiny openings and dark tacks stuck all over it.
the cell membrane is like the outside of a Baseball. If you think about it. It can also be a gate guarding a factory compound.
A fence around a house- it keeps things from getting out and in, protecting the house, and also decide what goes in and what comes out.

What is similar to a cell wall?
A cell membrane is similar to a cell wall in that it surrounds and protects the cell, providing structure and support. However, unlike a cell wall, a cell membrane is typically flexible and selectively permeable, allowing for the movement of substances in and out of the cell.
What structure controls the passage of substances into and out of the cell?
cell membrane
What Controls what moves in and out of the cell?
Cell membrane
Which contains the other cell membrane or phospholipid?
the cell membrane
What controls the entering and leaving of a cell?
cell (plasma) membrane
What are the analogies for cell membrane in a plant cell?
MY brother is very ugly. His name is Bob Big Beut. I kill yoou. Americans die. KaKa po po= Amerecain

What are analogies for the nuclear membrane?
A bodyguard because the nuclear membrane protects the nucleus just like a bodyguard protects celebrities
What structure controls the passage of substances into and out of the cell?
cell membrane
What Controls what moves in and out of the cell?
Cell membrane
Another name for plasma 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.
What is the thin flexible membrane around all cells?
The thin flexible membrane around all cells is called the cell membrane or plasma membrane. It serves as a protective barrier that regulates the passage of substances in and out of the cell.
Which contains the other cell membrane or phospholipid?
the cell membrane
What controls the entering and leaving of a cell?
cell (plasma) membrane
What is the outer boundary of a cheek cell called?
The outer boundary of a cheek cell is called the cell membrane or plasma membrane. It acts as a barrier, controlling the movement of substances in and out of the cell.
What is a cell membrane of?
There are multiple membranes in a cell. Two of them are the cell membrane and the nucleur membrane.
What is the outer boundary of an animal cell called?
The outer boundary of an animal cell is called the cell membrane or plasma membrane. It acts as a protective barrier, regulating the movement of molecules in and out of the cell.
