MEMBRANE TRANSPORT

• The plasma membrane of the living cell not only covers the cytoplasm but also controls the transport of water and solutes between the external and internal environments.
• For the cell to survive it takes up the nutrients from outside and release the internal substances outside. This process occurs by means of transport either through cell membrane or through proteins in the lipid bilayer.
• This transport process can be divided into two types
  • Passive transport 
  • Active transport
