    What type of cell division takes place in the functional megaspore initially in angiosperms?

    A) Homeotypic without cytokinesis

    B) Reductional without cytokinesis

    C)  Somatic followed by cytokinesis

    D) Meotic followed by cytokinesis

    Correct Answer: A

    Solution :

    Embryo sac is developed from the functional megaspore. The nucleus of functional megaspore undergoes  homotypic mitotic division without cytokinesis when eight nuclei are formed these undergo cell wall formation (except two polar nuclei). Megaspore is haploid therefore reduction (meiotic) division is not possible.
