Which of the following statements is not true regarding the mode of reproduction of organisms belonging to different classes of the kingdom fungi?
| 1. | Large number of members of deuteromycetes are decomposers of litter and help in mineral cycling |
| 2. | Sex organs are absent in basidiomycetes but plasmogamy is brought about by fusion of the nuclei of the gametes |
| 3. | The asexual spores produced by ascomycetes are conidia, produced exogenously on the special mycelium called conidiophores |
| 4. | In ascomycetes and basidiomycetes, an intervening dikaryon stage exists before the fusion of parental nuclei |
