Yard is to fence as cell is to membrane. Just like a fence surrounds a yard and allows certain objects in and out, a membrane surrounds the cell and only allows specific nutrients inside of it.
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.
The fence
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 cell wall is similar to a protective barrier or fence surrounding a house. It provides structural support and protection to the cell, similar to how a fence provides boundary and security to a house.
A cell membrane has a similar job to a cell wall in that it helps protect and support the cell, controls what enters and exits the cell, and maintains the cell's shape and structure.
the cell membrane is like a guard because it only allows chemicals in and out of the cell
