  1. Question 1

    Q1. White blood cells must undergo rapid changes in shape to squeeze through narrow capillary walls into infected tissues. Which cytoskeletal component enables this amoeboid movement?

    • A) Intermediate filaments
    • B) Microfilaments
    • C) Microtubules
    • D) Centrioles

    Answer: Microfilaments

    Explanation: Microfilaments (actin) are responsible for amoeboid movement and shape changes. Intermediate filaments are tempting but they provide static structural support, not movement.
