Answer

Brief Explanations:

  1. a. Amoeba engulfing food is active transport which requires energy as it goes against the concentration - gradient.
    • b. Since it requires energy, it is active transport.
    • c. Engulfing of particles is endocytosis.
  2. a. Amoeba expelling waste also requires energy as it may involve moving substances against a gradient.
    • b. As it needs energy, it is active transport.
    • c. Expelling waste from the cell is exocytosis.

Answer:

  1. a. Yes
    • b. Active
    • c. Endocytosis
  2. a. Yes
    • b. Active
    • c. Exocytosis
