Fungi show a great diversity in-

Options

A. Morphology
B. Habitat
C. Both a and b
D. Nutrition

Answer

To solve the question "Fungi show a great diversity in," we will analyze the options provided and understand the characteristics of fungi.

### Step-by-Step Solution:

1. **Understanding Fungi**:
- Fungi are classified as eukaryotic organisms. They can be unicellular (like yeasts) or multicellular (like molds and mushrooms).
- They lack chloroplasts, which means they do not perform photosynthesis.

2. **Diversity in Morphology**:
- Morphology refers to the form and structure of organisms. Fungi exhibit a wide range of morphological forms, from single-celled yeasts to complex multicellular structures like mushrooms.
- This indicates that fungi show significant diversity in their physical appearance and structure.

3. **Diversity in Habitat**:
- Fungi are known to be cosmopolitan, meaning they can thrive in various environments. They can be found in soil, water, air, and as symbionts or pathogens in plants and animals.
- This adaptability to different habitats shows that fungi have a great diversity in where they can live.

4. **Diversity in Nutrition**:
- Fungi are heterotrophic, meaning they obtain their nutrients by absorbing organic matter. They cannot produce their own food like plants (which are autotrophic).
- While nutrition is an important aspect, it does not reflect diversity in the same way morphology and habitat do.

5. **Conclusion**:
- Based on the analysis, fungi show great diversity in both morphology and habitat.
- Therefore, the correct answer is option 3: "both A and B" (morphology and habitat).

### Final Answer:
Fungi show a great diversity in both morphology and habitat. The correct option is **option 3: both A and B**.
