The structure mentioned in the question is cell membrane. The cell membrane can be described as a semi-permeable membrane which regulates the export and import of particles across the cell membrane. Some molecules move inside the cell along the concentration gradient by passive transport while other molecules move inside through active transport i.e against the concentration gradient.
The cell membrane is made up of phosphate head and fatty acid tails.
