  • Mention the difference between osmosis and difussion.
    Osmosis is only for transporting water molecules.
  • A ____ solution causes a cell to shrink because of osmosis.
    Hypertonic
  • This picture represents which type of cellular transport?
    Endocytosis
  • Which type of transport goes from an area of low concentration to high concentration that requires energy?
    Active Transport
  • _____ is the movement of molecules from a high concentration to a low concentration.
    diffusion
  • True or False: Phospholipids are made of hydrophilic (water-loving) heads and hydrophobic (water-hating) tails.
    True
  • If the cell is hypotonic the cell will
    swell/grow
  • What is Endocytosis?
    This is the process of engulfing (eating) the large particles
  • Active transport requires _____
    energy
  • True of False: The two main components of the cell membrane are hydrophobic tails and hydrophilic heads
    False
  • What is the process of moving water molecules across selectively permeable membranes?
    Osmosis

    Cell Membrane
  • Mention the passive transport used by water molecules
    Osmosis
  • What is happening in this picture?
    Exocytosis
  • What is happening in this picture?
    Endocytosis
  • Which direction would water move in a hypotonic state?  (Into the cell or out of the cell)
    Into the cell
  • When a cell has reached an isotonic solution it is said to be...
    in Homeostasis (equal)
  • True ro False: The cell membrane is formed of phospholipids and proteins only.
    False
  • Cell transport is classified in two types. Which are they?
    Passive and active transport
  • What are 3 ways that materials move through the Cell Membrane using Passive Transport?
    Diffusion, Osmosis, Facilitated Diffusion
  • Shrinking an object by removing water is an example of
    Hypertonic Solution
  • What is Facilitated Diffusion?
    The movement of substances across the membrane with the assistance of special transport proteins.
  • Mention the three types of passive transport
    Osmosis, diffusion and facilitated diffusion.
  • What is happening in this picture?
    Diffusion
  • Which type of transport goes from an area of high concentration to low concentration while requiring NO energy?
    Passive Transport
  • True or False: Cell transport can be passive or active.
    True
  • An object swells when water is abosorbed is an example of
    Hypotonic Solution
  • Your door to your home would be like a ___________ in a cell membrane.
    protein channel or carrier
  • This is an example of...
    Diffusion
  • True of False: Protein Pump is an example of active transport.
    true
  • Selective Permeability means..
    it allows some substances to pass through the membrane but not others
  • Which type of cell trasport is used by large molecules?
    Facilitated difussion.
  • Passive transport requires _____
    no energy
  • Which type molecules use difussion to cross into the cell?
    Small molecules like oxygen and carbon dioxyde.
  • Which is the difference between active and passive cell transport?
    Passive transport does not requiere energy, while aactive trasnsport does.
  • _____ transport does not require energy or ATP from the cell to operate.
    Passive
  • What type of transport involves the movement of water molecules through a membrane?
    Osmosis
  • What is Exocytosis?
    This is what allows large particles to exit the cell.
