cel membrane
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.
It would be the walls of the school or the fence around it.
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.
The protective fence that is characteristic of plant cells, but not animal cells, is the cell wall. The cell wall is a rigid outer layer made primarily of cellulose that provides structural support and protection to the plant cell. It helps maintain cell shape and prevents excessive water loss, distinguishing plant cells from their animal counterparts, which only have a flexible cell membrane.
A fence that keeps wolves from raging at you.
the cell membrane is like a guard because it only allows chemicals in and out of the cell
The fence around a cell wall is primarily formed by the cell membrane, which is composed of a phospholipid bilayer with embedded proteins. In plant cells, the cell wall itself is made up of cellulose, hemicellulose, and pectin, providing structural support and protection. In bacterial cells, the cell wall is primarily composed of peptidoglycan. Together, these components create a protective barrier that maintains the cell's shape and integrity.
I think the border of the city or like a fence or wall would be the best one I can think of.
True.
