A fence around a building it keeps bad stuff and the other stuff in
Like an egg.
The function of the cell wall is to protect the cell from foreign objects =]
The outer layer of a cell is the cell membrane or plasma membrane
homeostasis
The cell wall is the outer-most layer, found outside the cell membrane. Animal cells only have a cell membrane, not a cell wall. Plant, bacteria, fungi and algal cells usually have a cell wall, as well as some archaea.
It could be a gate. It is a gate because the door is the cell membrane. See you need to get past the cell wall before the cell membrane.
a building
The fence
I think the border of the city or like a fence or wall would be the best one I can think of.
If cell is a factory, mitochondria is its powerhouse
Nickname: "The fortress of the cell." Analogy: The cell wall is like the walls of a castle, providing structure, support, and protection to the cell, much like how castle walls protect the inhabitants inside.
A baseball analogy for a cell wall could be the outfield fence. Just like the fence separates the playing field from the spectators, the cell wall acts as a boundary that protects the cell and provides support. Additionally, like how the outfield fence can vary in height and thickness, cell walls in different organisms can have various compositions and structures.
If cell is a factory, mitochondria is its powerhouse
A castle. hard outer wall, important nobles inside. protected by knights, etc.
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.
A good analogy for a cell wall is either a city wall which protects the city from attack and holds it together. or possibly a brick wall of a building. which supports the building, protects it from harsh elements and only allows materials to enter through certain entrances and exits.
Hat on in winter...keeps everything protected or walls around a castle...keeps potential attacks at bay
