The Outer Envelope

Parallel lines of oval objects form a wall bridged by tendril like structures. Floating on either side of the wall are spherical objects. Caption: for larger molecules to get through.

Part of the "Inside the Living Cell" series. Describes the properties of the plasma membrane, how it governs the kinds of molecules that go in and out of cells, and how cells feed by engulfing (phagocytosis) and drinking in (pinocytosis) fluids. Also reviews membrane structure, osmosis, transport proteins, active transport, cell eating, cell drinking, and receptor proteins.
