Which of the following is used to produce SCP on commercial scale Chlorella Spirulina Methylophilus methylorophus All the above 2. Chlorella and Spirulina which are grown to harvest SCP are Unicellular green alga anf filamentous blue green alga respectively Filamentous blue green alga and unicellular green alga respectively Baker’s Yeast and Torula yeast respectively. Filamentous fungus and unicellular fungus respectively 3. Developing healthy plants from viral diseased plant by culturing meristems of axillary bud only meristems of terminal bud only meristems of apical and axillary buds parenchyma of root cortex or medulla 4. Meristem cultures are successfully made by scientists in Banana, Maize and Dahlia Banana, Sugarcane, Oranges Banana, Sugarcane, Potato Potato, Banana, Onion 5. Pomato is resulted due to meristematic tissue culture traditional plant breeding DNA recombination technology Somatic hybridixation 6. Totipotency was first experimentally demonstrated by Morgan Haberlandt F.C. Steward Stanley 7. The term totipotency was coined by F.C. Steward Hanstein Darwin Morgan 8. First plant produced during demonstration of totipotency was Raddish Carrot Maize Datura 9. During the production of aseptic seedings the seeds are surface sterilized with Sodium hypochloride 0.1 % mercuric chloride Potassium metabisulphate Copper oxychloride 10. Temperature required during autoclaving is 80°C 100 °C 140 °C 121 °C 11. Rhizogenesis is due to More auxin than cytokinin Gibberellin More cytokinin than auxin Abscisic acid 12. Caulogenesis is due to More auxin than cytokinin Gibberellin More cytokinin than auxin Abscisic acid 13. The technique of obtaining large number of plants through tissue culture is Micropropagation Hybridoma technology Cryopreservation Totipotency 14. The substance used for the encapsulation of the embryoids to produce artificial or systhetic seeds is Mercuric chloride Sodium hypochlorite Agar Sodium alginate 15. Female plants in Carica are produced in great numbers By growing seeds on culture medium containing gibberellins By growing seeds on culture medium containing auxins By excising the tissue from female plant and growing on the nutrient medium By excisting the tissue either from male or female plant and growing it in the nutrient medium containing auxins.
