  • from low concentration to high
    active transport
  • from high concentration to low
    passive transport
  • Phagocytosis is
    take in solid materials
  • a movement of water molecules from a higher concentration to a lower concentration
    osmosis
  • Diffusion is
    a movement of molecules from an area of high concentration to low concentration area until both sides are equal.
  • transport molecules out of the cell
    exocytosis
  • cigarette smoke is an example of
    diffusion
  • It is selectively permeable. It means
    some substances can move across the membrane, and some cannot.
  • tea bag placed in a cup of hot water is an example of
    diffusion
  • Endocytosis, exocytosis, sodium potassium transportations are examples of
    active transport
  • active transport requires no energy.
    false
  • The cell membrane is
    a border between the cell and its environment.
  • ... is an active transport of large particles into the cell
    Endocytosis
  • Pinocytosis -
    take in liquid materials
