    Question

    Which of the following is/are true with respect to

    Amoeba? I. It is a multi-cellular organism. II. It takes in food using temporary finger-like extensions called Pseudopodia. III. It forms a food vacuole around the food particle.
    A Only I Correct Answer Incorrect Answer
    B Only II and III Correct Answer Incorrect Answer
    C Only I and II Correct Answer Incorrect Answer
    D All of the above Correct Answer Incorrect Answer

    Solution

    I is incorrect as the Amoeba is a uni-cellular organism. Both II and III are correct. Amoeba takes in food using temporary finger-like extensions of the cell surface which fuse over the food particle forming a food-vacuole. Inside the food vacuole, complex substances are broken down into simpler ones which then diffuse into the cytoplasm. Hence, option B is correct.
