In what way is the cell membrane like a gatekeeper? (The picture It just because I wanted to put it TwT)

The membrane is a gatekeeper as it only allows access to selected nutrients or cells, if it wants one type of nutrient to process, it will only choose that nutrient!

Hope this helps, if not, comment below please

The cell membrane controls how materials move into or out of a cell, just like a gatekeeper controls the flow of traffic into and out of a parking lot. Movement of substances through a cell membrane WITHOUT using the cell's energy ; includes diffusion, osmosis, and facilitated diffusion.
