The most important property of yeast is: Distillation Fermentation Oxidation Reduction Explanation:Yeast is renowned for its ability to ferment sugars, producing alcohol and carbon dioxide, which is crucial in baking and brewing industries. 3. Early blight of potato is caused by: Alternaria solani Phytophthora infestans Albugo candida Helminthosporium oryzae Explanation:Early blight of potato, characterized by dark spots on leaves and stems, is caused by the fungus Alternaria solani. 4. Zoogametes are not found in: Funaria Rhizopus Cycas Fern Explanation:Zoogametes, motile gametes, are not found in Rhizopus, which reproduces through non-motile spores and gametes. 5. Metulae are found in: Aspergillus Penicillium Saccharomyces Agaricus Explanation:Metulae are secondary branches in the conidiophores of Penicillium, which bear chains of conidia (asexual spores). 6. Late blight of potato is caused by: Phytophthora infestans Alternaria solani Fusarium moniliforme Albugo candida Explanation:Late blight of potato, responsible for the Irish potato famine, is caused by the oomycete Phytophthora infestans, leading to severe crop losses. 7. The two conjugating gametangia of Rhizopus are: Morphologically different Physiologically different Morphologically and physiologically similar Both morphologically and physiologically different Explanation:The conjugating gametangia of Rhizopus are physiologically different, meaning they have distinct functional roles during sexual reproduction. 8. Who discovered heterothallism in fungi? Bessey Robert Brown Alexopoulos Blakeslee Explanation:Heterothallism, the requirement of two different mating types for sexual reproduction in fungi, was discovered by Albert Blakeslee. 9. Yeast belongs to class: Ascomycetes Deuteromycetes Basidiomycetes Zygomycetes Explanation:Yeast is classified under Ascomycetes, a class of fungi known for producing spores in sac-like structures called asci. 10. The spores which are formed in the sporangium of Rhizopus are: Non-ciliated Ciliated Biflagellated Multinucleate-flagellated Explanation:The spores formed in the sporangium of Rhizopus are non-ciliated, meaning they lack hair-like structures for movement.
