Yeast reproduces during fermentation mainly by

  • A.Budding
  • B.Binary fission in the manner of bacteria
  • C.Producing spores that are released into the liquid
  • D.Fragmenting its filaments into separate pieces

Answer: A

Correct answer: Budding

Saccharomyces reproduces asexually by budding: a daughter cell forms as an outgrowth of the mother, receives a nucleus, and separates, leaving a bud scar behind. Binary fission is the bacterial mechanism, and sporulation in yeast is a response to starvation rather than the normal route of growth.
