nope
it means it let some materials pass through it while block the way of others for example; the outer shell of egg
Osmosis. Osmosis is the diffusion of water through a selectively permeable membrane. I'm assuming you mean active transport of plasma into a red blood cell.
The cell membrane only allows certain molecules through.

Because plasma membrane allows only certain solute to move into the cell and outside the cell
it allows some substances to pass through but blocks the passage of others.

DefinitionnounA membrane that is selectively permeable, i.e. being permeable to only certain molecules and not to all molecules.SupplementAn example of such membrane is the cell membrane wherein it allows passage of only certain types of molecules by diffusion and occasionally by facilitated diffusion.by~paula razon (facebook)!!!

Selectively permeable refers to a cell membrane that will let certain things in and out of the cell, but block other things.
it means that any biological membrane allows only certain solute or we can say nutrients that are required by cell, to enter into cell through itself and not other unnecessary particles hrmful to cell.. Such property is called selectively permeable or semi permeable...
I assume you mean semi-permerable membrane that is permeable to the solution (water) but not the solute (salt). Osmosis can only occur if the membrane does NOT allow salt to pass through. Osmosis is the movement of water across a semi-permeable membrane from an area of low salt concentration to higher salt concentration.

If you break down the two words, selective means to only pick certain things, and permeable means to let pass through. When you talk about something being "selectively permeable", it usually refers to a cell membrane because it only lets in certain nutrients and lets out proteins and what not. I hope this answers your question.
