'Clamp connections' are observed in

Step-by-step solution

'Clamp connections' 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 promycelium with terminal sporangium. In Oomycetes one of the flagellum is of tinsel type and the other of whipl
