Assertion : Slime moulds show alternation of generation. Reason : The sporangia bearing slime moulds represents haplophase.A. If both the assertion and the reason ate true but the reason is not correct explanation of the assertionB. If both the assertion and the reason ate true and the reason is a correct explanation of the assertionC. If the assertion is true but the reason is falseD. If both the assertion and reason are false |
|
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. |
