    'Clamp connection' are observed in :

    A)  Basidiomycetes              

    B)  Zygomycetes

    C)  Ascomycetes                   

    D)  Oomyceles

    Correct Answer: A

    Solution :

                     "Clamp connection" are observed in basidiomycetes (club fungi). During nuclear divisions of the dikaryotic cell, special structures called the clamp connections are formed. These clamp connections ensure that the sister nuclei of the dikaryon, at each division, separate into daughter cells. Torula stage of fungus is observed in zygomycetes. In zygomycetes the zygospore germinates to produce a hypha, the promyceHum which terminal sporangium. In oomycetes one of the flagellum is of tinsel type and the other of whiplash type. The hyphal wall chiefly consists of\[\text{ }\!\!\beta\!\!\text{ }\] glucans and cellulose and not chiton. The mycelium is extensive and coenocytic. In ascomycetes the spores of the sexual stage (meiospores) which are known as the ascospores are endogenous in origin. They are produces within sac-like structures called and which very in shape.
