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

To determine how yeast multiplies, we need to consider its common methods of reproduction. Yeast is a type of fungus, and it primarily reproduces asexually. Among the options provided, the method yeast uses is:

1. Budding: This is the correct answer. Yeast primarily reproduces through budding, a form of asexual reproduction. In this process, a new cell, or "bud," forms on the parent yeast cell, gradually enlarges, and eventually detaches to become a separate organism. During budding, the nucleus of the yeast cell divides so that the new bud receives a copy of the genetic material.
2. Binary Fission: This method is typical in prokaryotic organisms like bacteria, not in yeast. In binary fission, the organism divides into two equal-sized offspring. Yeast does not utilize this method as its primary form of reproduction.
3. Multiple Fission: This process involves a single organism dividing into multiple offspring simultaneously. It is more typical in certain protists and is not how yeast multiplies.
4. Fragmentation: Fragmentation involves breaking into pieces, each of which can develop into a new organism. This is common in some multicellular and filamentous fungi, but not in unicellular yeast.

Among the options, budding is the most appropriate method by which yeast multiplies.
