The diagram shows the presence of a pathogen amongst RBCs in the peripheral blood smear of a patient. Even though the shape is very easy to identify, the structure highlighted in the circle should enable you to identify the pathogen easily. It is:
1. | Trypanosoma | 2. | Plasmodium |
3. | Schistosoma | 4. | Clonorchis |
(i) | It was given by George Bentham and Joseph Dalton Hooker |
(ii) | It was based on natural affinities among the organisms |
(iii) | It takes into account not only the external features but also internal features |
(iv) | Internal features like ultrastructure, anatomy, embryology and phytochemistry are also considered |
(v) | Evolution is also taken into account |
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 |
