The component that helps transfer substances across the membrane that I believe you are talking about, are the embedded protein channels. They help move larger particles across the cell membrane such as sodium because they are too large to move through the phospholipid bilayer.
Facilitator proteins, also called protein channels.
I just had a quiz on this today and I think the answer was either osmosis or facilitated diffusion. Look up both words and it will probably tell you.
Applied pressure would help moving of material across membrane agains the osmotic pressure.
endoplasmic reticulum
a cell membrane controls movement of substances in and out of the cell.
The cell membrane helps a cell maintain homoeostasis by regulating the movement of substances in and out of the cell. The cell membrane is a lipid bilayer which is selectively permeable to substances.
Cell membrane
A plant cell has a cell membrane which controls the movement of substances in and out of the cell. :D
The cell membrane allows the movement of substances in and out of the cell while the cell wall just gives the plant cell its firm shape.

controls the movement of substances into and out of the cell. Avios
any large molecule is moved out of the cell from the cell membrane
