The cell membrane - the outer layer in animal cells and the layer beneath the cell wall in plants that is made up of a double layer of phospolipid molecules. The term semipermeable means that the outer layer only allows certain substances into and out of the cell, not everything.
Permeable layers allow either all or only certain things in and out. The ground is permeable because it allows water to sink through it. Skin is also permeable because it takes in oxygen and liquids but it keeps other foreign objects out. The skin can let out waste by sweating.
The semipermeable layer that surrounds all cells is called the cell membrane or plasma membrane. It consists of a phospholipid bilayer with embedded proteins and acts as a barrier, controlling the movement of substances in and out of the cell.

A fully permeable layer is a layer that allows all substances to pass through. A partially permeable membrane is a membrane that only allows some substances to infiltrate.

An aquifer forms when groundwater pools between a permeable layer and an impermeable layer.

Permeable layer
Cell membrane is made up of lipid bi layer. It is selectively permeable to some substances only. It plays very important role in integrity of the cell.
