Question

Explain the importance of regulating what enters and exits the cells.

Answer 1

~remember 9/11~

Hi.

From the top of my head, I think it is important that the cell membrane regulates what enters and exits the cell because I think doing that helps the cell avoid infections and avoid any important organelles escaping. It might also help with not letting contagious diseases spreading to other cells, maybe? Not sure about that one. xP

Answer 2

"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"

So I guess also so it can block polar molecules and let non-polar molecules eneter? :D
