Answer» Correct Answer - C Slime moulds exhibit alternation of generation. The diploid plasmodium is a sporohyte. Under certain condition it bears sporangia. The sporangia bearing plasmodium and spore producing sporangia constitute the sporophyte generation. It is displophase reduction division takes place at the time of differentiation of resting spore. The resting spores germinate to produce the haploid, uninucleate swarm cells or myxamoeboa. The latter meet and fuse in pairs to form a zygote. The haploid resting spores and the swarm cells or myxamoeba represent the haploid or gametophyte generation. |
