It makes a boundary by the cytoplasm and goes in and out of the cell.
Permeability
What you are considering when you are referring to how easily materials can pass through a membrane is how permeable the cell wall or membrane is.
proteins
A cell controls what moves through the membrane by means of membrane proteins embedded in the phospholipid bilayer.The things that can easily move in and out of the cell through the membrane are gases, like oxygen and carbon dioxide, and water.
The cell membrane who ever is looking this up the cell membrane is what let things go in and out of the cell it is also known as the traffic cop:) if need any more answers look up the answer by typing in the search bar up above Thank you :)
of a cell? the cell membrane.
