Question

14. The prions are the abnormal shape protein which cause the disease like spongiform encephalopathies. Hence option c is correct  

15. Excavata are the organism having tetramembraneous chloroplasts, some with hairy flagellae, some with pseudopods; some with cuplike indentations in the cell membrane. Hence option a is correct.

16. The protist are unicellular, colonial, and some multicellular organisms that lack true tissues. Hence option c is correct.

17. Trypanosoma is the protest which cause chagas diseases and sleeping sickness disease. Hence option d is correct.

18. Apicomplexan is not a unicellular algae. Hence option a is correct.

19. Fungi are the group of organism which are heterotrophs, multicellular and having chitin in their cell wall. Hence option a is correct.

20. Dikaryotic algae are the fungi with two nucleus. Hence option c is correct.

21. The hyphae are complete mass of fungal cell elements. Hence option b is correct.

22. Basidomycota are the fungi which produced cup like structure. Hence option b is correct.

23. A lichens are the symbiotic relationship between fungus and cynaobacteria. Hence option d is correct.

24. The is a false statement as slime molds are not considered as a part of fungi. Hence option b is correct.
