plasma membrane

Definitions

  • WordNet 3.6
    • n plasma membrane a thin membrane (a double layer of lipids) enclosing the cytoplasm of a cell; proteins in the membrane control passage of ions (like sodium or potassium or calcium) in and out of the cell "all cells have a cell membrane"

More specifically, diffusion is accomplished through the plasma membrane by very small, normally uncharged molecules such as water.
Biological Concepts Instrument (BCI): A diagnostic tool for revealing student thinking
When talking about cells, the barrier is usually a membrane such as the plasma membrane. Small, uncharged molecules such as O2, or CO2 can easily pass through a membrane that is permeable to those substances.
