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 perme â¦ able, it usually refers to a cell membrane because it only lets in certain nutrients and lets out proteins and what not. In human terms, a DOOR is permeable, but a wall is not. [and technically speaking, sometimes a window is permeable]    So, if a membrane is selectively permeable this means that only some things can go in or out through the membrane.
