NEET PREVIOUS YEARS QUESTIONS-EXPLANATIONS<\/strong><\/p>\n\n\n\n

1. (d)   <\/strong>Pseudopodia are locomotory structures in sarcodines (amoeboid).<\/p>\n\n\n\n

2. (a)    <\/strong>Saccharomyces <\/em>i.e. yeast is an eukaryote (unicellular fungi). Mycobacterium is a bacterium.<\/p>\n\n\n\n

 Oscillatoria <\/em>and Nostoc <\/em>are cyanobacteria.<\/p>\n\n\n\n

3. (c)    <\/strong>Ciliates differs from other protozoans in having two types of nuclei. E.g., Paramoecium <\/em>have two types of nuclei i.e. <\/em>macronucleus & micronucleus.<\/p>\n\n\n\n

4. (b)   <\/strong>Diatoms are the chief producers or the most common form of phytoplankton in the ocean. They utilise inorganic nutrients to form proteins, fats and organic material & provide food for various sea creatures.<\/p>\n\n\n\n

5. (d)   <\/strong>In Agaricus <\/em>(a genus of basidiomycetes), basidiospores or meiospores are produced exogenously. Neurospora<\/em> (a genus of ascomycetes) produces ascospores as meiospores but endogenously inside the ascus). Alternaria <\/em>(a genus of deuteromycetes) does not produce sexual spores. Saccharomyces <\/em>(unicellular ascomycetes) produces ascospores, endogenously.<\/p>\n\n\n\n

6. (c)    <\/strong>Sticky character of the bacterial wall is due to glycocalyx which is rich in glycoproteins.<\/p>\n\n\n\n

7. (b)   <\/strong>Mycoplasmas are smallest, prokaryotes lacking cell wall and are pleomorphic in nature. These are pathogenic to both plants and animals.<\/p>\n\n\n\n

8. (d)   <\/strong>Archaebacteria are able to survive in harsh conditions due to the presence of branched lipid chain in cell membrane that reduces fluidity of cell membrane. It includes halophiles which are exclusively found in saline habitats.<\/p>\n\n\n\n

9. (c)    <\/strong>Viroids are sub-viral agents as infectious RNA particles, without protein coat.<\/p>\n\n\n\n

10. (b) <\/strong>All unicellular eukaryotic organism like diatoms, desmids (chrysophytes), euglenoids, dinoflagellates<\/p>\n\n\n\n

and slime mould are included in protista.<\/p>\n\n\n\n

11. (a)<\/strong><\/p>\n\n\n\n

12. (c) <\/strong>Eubacteria are the true bacteria.<\/p>\n\n\n\n

13. (d)<\/strong><\/p>\n\n\n\n

14. (d) <\/strong>Nuclear envelope is not found in a prokaryotic cell.<\/p>\n\n\n\n

15. (a) <\/strong>Fimbriae help bacteria to get attachment with rocks or host body to get establishment and nutrition.<\/p>\n\n\n\n

16. (c) <\/strong>The kingdom monera possesses unicellular organisms (e.g – bacteria) having no nuclear membrane.<\/p>\n\n\n\n

17. (d) <\/strong>In chrysophytes, the cell walls form two thin overlapping shells held together. The body of diatoms<\/p>\n\n\n\n

            appears like soap box due to overlapping shells.<\/p>\n\n\n\n

18. (d) <\/strong>Class-deuteromycetes contains imperfect fungi which play an important role in decomposition of<\/p>\n\n\n\n

            Organic wastes.<\/p>\n\n\n\n

19. (a) <\/strong>The spores are non-motile in Mucor<\/em>.<\/p>\n\n\n\n

20. (b) <\/strong>Morel and truffles are used as food and they are members of ascomycetes fungi.<\/p>\n\n\n\n

21. (a) <\/strong>Alternaria <\/em>belongs to class – deuteromycetes, which lack sexual reproduction. Asexual reproduction<\/p>\n\n\n\n

            Takes place by conidia produced on conidiophores.<\/p>\n\n\n\n

22. (d) <\/strong>Anabaena <\/em>is a cyanobacteria which lack a true nucleus because of absence of nuclear membrane.<\/p>\n\n\n\n

23. (d) <\/strong>Lichens cannot grow in the place where sulphur dioxide, pollutant is available in the environment.<\/p>\n\n\n\n

24. (a)<\/strong><\/p>\n\n\n\n

25. (a)<\/strong><\/p>\n\n\n\n

26. (a) <\/strong>Archaebacteria differ from other bacteria in having a different cell wall structure. They lack<\/p>\n\n\n\n

peptidoglyan in cell wall and possess a monolayer of branched fatty acids attached to glycerol by ether bonds in their cell membranes.<\/p>\n\n\n\n

27. (b) <\/strong>Motile bacteria have thin filamentous extensions from their cell wall called flagella.<\/p>\n\n\n\n

28. (b) <\/strong>Several mushrooms such as Amanita muscaria<\/em>, Psilocybe mexicana <\/em>and Panaeolus <\/em>spp. secrete<\/p>\n\n\n\n

hallucinogenic substances like psilocybin and psilocin.<\/p>\n\n\n\n

These substances may destroy brain cells and perception power of human beings.<\/p>\n\n\n\n

29. (b)<\/strong><\/p>\n\n\n\n

37<\/strong>.       Viroids are infectious nucleic acid contains only ssRNA  <\/p>\n\n\n\n

38<\/strong>.    Fusion of protoplasm between two motile or non \u2013 motile gametes is called plasmogamy<\/p>\n\n\n\n

39        <\/strong>Mycoplasma are bacteria with out cell wall.<\/p>\n\n\n\n
