    The amoeboid movement results from

    A)  interactions among actin, myosin and ATP, etc

    B)  coordinated beats of cilia

    C)  whip-like action of flagella

    D)  action by the mitotic spindle, similar so, what happens during mitosis and meiosis

    Correct Answer: A

    Solution :

                    Amoeboid movement is the most common mode of locomotion in eukaryotic cells. Molecular mechanism involves participation of microdomain signalling. As, microdomains trigger and maintain active polymerisation of actin filaments, their propagation leads to interaction with myosin that generates retrograde flow. ATP is utilised in this process.
