Which of the following information can be used to distinguish yeast from bacterial cells?

Options

A. Fungi are more significant animal pathogens than bacteria
B. Unlike fungi, bacterial species contain rigid cell walls
C. Yeast are much larger than bacterial cells
D. Fungi species lack internal cell structures

Answer

To distinguish yeast from bacterial cells, we can follow these steps:

1. **Understand the Basic Characteristics**:
- Yeasts are single-celled eukaryotic organisms belonging to the kingdom Fungi.
- Bacteria are single-celled prokaryotic organisms.

2. **Evaluate the Options Given**:
- The first option states that fungi are more significant animal pathogens than bacteria. This is incorrect as bacteria are generally more pathogenic to animals.
- The second option claims that unlike fungi, bacterial species contain rigid cell walls. This is misleading because both fungi and bacteria have cell walls, but the composition differs (bacteria have peptidoglycan).
- The third option states that yeasts are much larger than bacterial cells. This is correct; yeast cells are typically larger than bacterial cells.
- The fourth option mentions fungal-like internal cell structures. This is incorrect because while yeasts are fungi, their internal structures differ from those of bacteria.

3. **Identify the Correct Distinguishing Feature**:
- The distinguishing feature that can be used to differentiate yeast from bacterial cells is that yeasts are generally larger than bacterial cells.

4. **Conclude the Answer**:
- Therefore, the correct answer is that "yeast are much larger than bacterial cells."
