Oscillatoria and Nostoc are cyanobacteria.
3. (c) Ciliates differs from other protozoans in having two types of nuclei. E.g., Paramoecium have two types of nuclei i.e. macronucleus & micronucleus.
4. (b) 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.
5. (d) In Agaricus (a genus of basidiomycetes), basidiospores or meiospores are produced exogenously. Neurospora (a genus of ascomycetes) produces ascospores as meiospores but endogenously inside the ascus). Alternaria (a genus of deuteromycetes) does not produce sexual spores. Saccharomyces (unicellular ascomycetes) produces ascospores, endogenously.
6. (c) Sticky character of the bacterial wall is due to glycocalyx which is rich in glycoproteins.
7. (b) Mycoplasmas are smallest, prokaryotes lacking cell wall and are pleomorphic in nature. These are pathogenic to both plants and animals.
8. (d) 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.
9. (c) Viroids are sub-viral agents as infectious RNA particles, without protein coat.
