Answer» \tPLASMOGAMY :\xa0Plasmogamy is a stage in the sexual reproduction of fungi, in which the cytoplasm of two parent cells (usually from the mycelia) fuses together without the fusion of nuclei, effectively bringing two haploid nuclei close together in the same cell.\tDIKARYON :\xa0The\xa0dikaryon\xa0is a nuclear feature which is unique to some fungi. The green alga Derbesia has been long considered an exception, until the heterokaryotic hypothesis was challenged by later studies. Compatible cell-types can fuse cytoplasms (plasmogamy).\tDIKARYOPHASE :\xa0\xa0the phase of the life cycle of a fungus (as the rusts) characterized by the dikaryotic condition.\tISOGAMOUS :\xa0Many algae and some fungi have\xa0isogamous\xa0gametes. In most sexual reproduction, as in mammals for\xa0example, the ovum is quite larger and of different appearance than the sperm cell. This condition is called anisogamy. "isogamy."\tANISOGAMOUS :\xa0Anisogamy\xa0(also called heterogamy) is the form of sexual reproduction that involves the union or fusion of two gametes, which differ in size and/or form. (The related adjectives are\xa0anisogamous\xa0and anisogamic). Hi Sia, please tell how you study to achieve your aim Thanks!!☺☺ |
