Question
Define intracellular transport and extracellular transport.

Answer

  1. Intracellular transport: In Parameocium, Amoeba, root hair cells of many plants and WBCs in animals, transportation of materials occurs within the cell due to the streaming movement of the cytoplasm known as cyclosis. This is known as intracellular transport.
  2. Extracellular transport: In roundworms there are no blood vessels and the body fluid is moved around the viscera by contraction of body wall and muscles. This is extracellular transport.
