How do yeast reproduce?

• A. Budding
• B. Mitosis with fission
• C. Binary fission
• D. Fragmentation

Answer: (A)

Yeast reproduce primarily by budding, an asexual process where a small outgrowth forms on the surface of the parent cell. The nucleus divides by mitosis, the bud enlarges while receiving a portion of cytoplasm and organelles, and eventually the bud separates to become an independent cell. This produces an asymmetric division, with the new cell starting small and growing to the size of the parent. This differs from binary fission or “mitosis with fission,” which would imply an even split of the cell rather than a protruding bud. Fragmentation describes breaking a filament into pieces to form new organisms, which is characteristic of some multicellular fungi, not the unicellular yeast budding commonly studied.
