Question

Yeast multiplies by which of the following methods?

• A. Fragmentation
• B. Binary Fission
• C. Multiple Fission
• D. Budding

Hint:

Yeast reproduction = Budding. Small bud forms → Grows into new cell.

Answer 1

The Correct Option is D

Concept: Yeast is a unicellular fungus that reproduces asexually by forming a small outgrowth from the parent cell. This process is called budding. Explanation:

• In budding, a small bulge or bud appears on the parent yeast cell.
• The nucleus divides and one daughter nucleus moves into the bud.
• The bud grows and eventually separates to form a new yeast cell.

Why Other Options Are Incorrect:

• (A) Fragmentation → Seen in organisms like \textit{Spirogyra}.
• (B) Binary fission → Common in bacteria and amoeba.
• (C) Multiple fission → Seen in organisms like \textit{Plasmodium}.

Conclusion: Yeast multiplies by budding, where a new individual develops as a small outgrowth from the parent cell.
