Model of a cell plasma membrane

Plastic organelle model of cell plasma membrane (plasma lemma, cell membrane)

The cell or plasma membrane of a cells controls the movement of substances in and out of the cell. Only certain substances can move across the barrier. Receptor molecules control this process. The membrane also provides some structural support.

This model, among others, was made for a Science Museum gallery called ‘Cells, Molecules and Life’ which opened in 1986 and closed in 1999. The gallery was sponsored by the Biochemical Society to celebrate their 75th anniversary.
