  • kind of transport that diffuse down concentration gradient From (high) concentration to (low) concentration
    Passive transport
  • Together, the phospholipids in the bilayer create a “sea” in which other molecules can float, like apples floating in a barrel of water creating a model called
    The fluid mosaic model
  • What kind of microscope that directs electrons over the surface of the specimen, producing a three-dimensional image
    SEM " scanning electron microscope "
