because some molecules are bigger then othersand won't diffuse into the cell... hope that helps

How does the composition of the cell membrane help regulate the movement of substances into and out of the cell?
They pass through channels in the cell membrane.
What types of membrane allow solvent molecules to pass through but do not allow solute molecules to pass through?
A membrane that does not allow substances through is impermeable. One that allows some substances, but not others, is semipermeable or selectively permeable.
What does it mean for a cell membrane to be selectively permeable?
it allows some substances to pass through but blocks the passage of others.
What characteristic of cell membrane allows some substances to pass through them but not others?

The neuron's cell membrane permits some substances to pass through but not others this is because the membrane is?
One of the characteristics of a cell membrane is that it is semi-permeable. As such, it is able to limit what can get into and out of the cell.
What does a selectively permeable membrane do?
A selectively permeable membrane allows some substances through it and does not allow others.Allows certain substances to pass but not others

What a role of the plasma membrane in maintaining the internal balance of the cell?
It is a selectively permeable membrane, meaning it allows certain substances to pass through it but not others.
A membrane that allows some substances to pass through while excluding others would be called?
selectively permeable
