Selectively permeable means that only certain objects can pass through. I've encountered that phrase in cell Biology, when talking about cell membranes. The cell membrane is made of phospholipids that only allow certain substances through. Water can pass through because the molecules are small enough to pass through small holes in the membrane. Other molecules, such as sodium or potassium, can be transported using protiens.

What does the term selectively permable mean?
"Selectively permeable" refers to a membrane that allows certain substances to pass through while blocking others. This selectivity is based on the size, charge, or other properties of the molecules trying to cross the membrane. An example is a cell membrane, which permits the passage of specific molecules necessary for the cell's function while blocking others.
