    In yeast, the sexual reproduction is by conjugation. After fusion, the zygotic nucleous divides meiotically and forms haploid spores. The unicellular structure with haploid spores is

    A)  sporangium      

    B)  gametangium

    C)  ascus             

    D)  zoosporangium

    Correct Answer: C

Ascospores are formed by the sexual fusion of two hyphae of opposite mating types.
