It means a membrane (thin flexible barrier of some kind) that substances can cross.

I means that the membrane will allow substances, usually liquids, to pass through It. For example when you rub sunblock onto your skin some of it is absorbed by the skin. The classic experiment is you have a glass open topped vessel filled with coloured liquid and secured by pigskin then immersed in clear water. Eventually the colour will seep out as the pigskin, being a membrane, is semi-permeable.

A membrane is like a thin barrier or wall, like cling wrap, or a cell wall, etc.
Permeable means that things can pass through it.
So a cell wall, for example, is a permeable membrane because it contains the cells contents yet it still allows various substances to pass through.

A membrane is something that encapsulates. There is no such thing as a permeable membrane but there are semipermeable membranes that allow transfer of molecules in and out of the membrane.

It means that the membrane (think skin) is permeable (things can flow in and out of it).

A permeable membrane is some sort of skin (or skin-like material) that allows liquids to pass or diffuse through it.
Not always liquids, that is, but usually.

It means that stuff can get thru it, as in gas permeable means some gas can get in.

A thin sheet of material that allows - especially liquids - to pass or diffuse trough.

It's a thin layer which still allows air and moisture through it.
