Is a cell membrane more like a brick wall or a chain-link fence? Why?

chain-link fence

Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.

Chain-link fence

Explanation:

Cell membranes are barriers that decide which molecules enter and exit the cell, and how much of them come in. So things are able to pass through them.

If it were a brick wall, it would not let anything pass through.

So it is more like a chain-link fence, but with more control over what passes through it.

the answer u all are looking for is 4000000000000000000000 million years.
