(REPOST)if something needed to enter the cell and couldn't go through the phospholipid bilayer, how else could it enter the cell?

by being facilitated

Explanation:

If something needs to enter the cell and could not go through the phospholipid bilayer, it could be assisted through a process known as facilitated diffusion.

Facilitated diffusion involves the passive movement of molecules that will ordinarily not pass through the phospholipid bilayer of the cell membrane through the help of the channel or carrier proteins.

If the phospholipid bilayer will not allow some molecules to pass through it as a result of a concentration gradient, the channel/carrier proteins form a special passage and the molecule is facilitated by such passage to move across the membrane.
