Oidia resemble yeast in

Options

A. fermentation
B. sexual reproduction
C. being diploid
D. all of these

Answer

**Step-by-Step Solution:**

1. **Understanding Oidia**: Oidia are a type of asexual spores produced by certain fungi. They are formed through the fragmentation of fungal hyphae, which are the thread-like structures of a fungus.

2. **Understanding Yeast**: Yeast is a single-celled eukaryotic organism that belongs to the kingdom Fungi. It is commonly known for its role in fermentation.

3. **Commonality Between Oidia and Yeast**: Both Oidia and yeast are involved in the process of fermentation. Fermentation is a metabolic process that converts sugars into alcohol and carbon dioxide through the action of microorganisms.

4. **Fermentation Process**: In fermentation, organic substrates (like sugars) undergo chemical changes to produce various products, such as alcohol in the case of yeast. This process is widely used in food production, such as in baking bread and brewing wine.

5. **Conclusion**: Therefore, Oidia resemble yeast primarily in their ability to participate in fermentation.

**Final Answer**: Oidia resemble yeast in fermentation.
