The dough used for making bread is fermented using baker's yeast, which consists of which of the following microbes?
Solution
Option 1 -> Baker's yeast (Saccharomyces cerevisiae) is a single-celled fungus that ferments sugars.
Option 2 -> Bacteria are prokaryotic microorganisms, not yeast.
Option 3 -> Viruses are non-cellular entities that cannot perform fermentation.
Option 4 -> Parasites depend on hosts; yeast is a free-living organism, not a parasite.
Hence, Option 1: fungus -> Baker's yeast is Saccharomyces cerevisiae, a unicellular fungus that ferments sugars in dough, producing carbon dioxide gas that causes the bread to rise and alcohol (which evaporates during baking) -> correct
