Practice question

Zygomycetous fungi termed conjugation fungi highlight sexual process where two compatible hyphal tips of opposite mating types recognize via pheromones, adhere and conjugate forming progametangia that fuse completely merging cytoplasms. Term conjugation refers to temporary union of gametangia producing zygospore, reminiscent of bacterial conjugation but involving whole hyphal compartments not just DNA transfer. Club fungi Basidiomycota bear basidia, sac fungi Ascomycota asci, imperfect fungi Deuteromycota lacking sexual phase. Therefore alternative name conjugation fungi aptly describes zygomycete sexual reproduction via direct hyphal conjugation and protoplasmic fusion culminating in dormant zygospore.
