C) Mycelium \[\to \]promycelium \[\to \]germ spores\[\to \]germ sporangium
D) Promycelium \[\to \]mycelium \[\to \]germ sporangium \[\to \]zygospores
Correct Answer: A
Solution :
Life cycle of Rhizopus is happid or haplontic. On germination, the thick zygosporangium wall and exospore crack Opan. The contents of the zygospore still surrounded by the endospore emerge in the form of a small upright hypha, the promycelium. The promycelium bears the germ sporangium at its top. The germ sporangium produces either (+) or (-) strain germ spores or both of them. Each germ spore on falling on a suitable substratum germinates to form the haplomycelium.You need to login to perform this action.
