Yeast grows more quickly in :-

Options

A. Salt water
B. Sugar solution
C. Double distilled water
D. Marine water

Answer

**Step-by-Step Solution:**

1. **Identify the Organism**: The question asks about yeast, which is a type of fungus that belongs to the Ascomycetes group.

2. **Understand Yeast Growth**: Yeast grows primarily through a process called budding. This is a form of asexual reproduction where a new organism develops from an outgrowth or bud on the parent organism.

3. **Metabolic Process**: Yeast is known to undergo anaerobic respiration, which means it can break down carbohydrates without the presence of oxygen. This process is known as fermentation.

4. **Nutritional Requirements**: For yeast to grow quickly, it requires a source of carbohydrates. A sugar solution provides these carbohydrates, which yeast can ferment to produce energy.

5. **Evaluate Options**:
- Double distilled water: Lacks nutrients and carbohydrates, hence yeast cannot grow.
- Marine water: Contains salt, which is not suitable for yeast growth.
- Salt water: High salinity can inhibit yeast growth.
- Sugar solution: Rich in carbohydrates, allowing yeast to ferment and grow quickly.

6. **Conclusion**: The best environment for yeast to grow quickly is in a sugar solution due to the availability of carbohydrates necessary for fermentation.

**Final Answer**: Yeast grows more quickly in a sugar solution.
