Kingdom Protista was proposed by Ernst Haeckel in 1866 as ‘the kingdom of primitive forms’. This kingdom forms a link between the kingdom Fungi, Plantae, and Animalia. Select the option which is incorrectly matched for slime moulds and their plant, animal or fungi like features:
1. Naked plasmodium-Animal like feature
2. Spore with true wall - Plant like feature
3. Formation of fruiting body-Fungi like feature
4. Formation of plasmodium-Protozoan like feature
1. Naked plasmodium-Animal like feature
2. Spore with true wall - Plant like feature
3. Formation of fruiting body-Fungi like feature
4. Formation of plasmodium-Protozoan like feature

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 |
