Cell membrane have proteins embedded in them that act as channels for things to enter and leave the cell. Furthermore, the fact that the membrane is non-polar will block any polar molecules from entering but will allow non-polar molecules such as hormones to enter.

How does a cell control what enters and leaves?

A cell controls what enters and leaves through its selectively permeable cell membrane. This membrane allows only specific molecules to pass in and out through various mechanisms like active transport, passive transport, and facilitated diffusion. Additionally, the cell may use protein channels or pumps to regulate the movement of substances in and out of the cell.
