Different organisms belonging to different orders are placed in a single class due to the fact that

Options

A. They have all similar morphological and reproductive characters
B. They have similar place of origin
C. They share a common habitat
D. They have few similar or common characters

Answer

To answer the question of why different organisms belonging to different orders are placed in a single class, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Taxonomy**: Taxonomy is the science of classification of living organisms. It organizes biological diversity into hierarchical categories.

2. **Taxonomic Hierarchy**: The hierarchy starts from the broadest category, which is the Kingdom, and narrows down to the species. The order of classification is:
- Kingdom
- Phylum
- Class
- Order
- Family
- Genus
- Species

3. **Definition of Class**: A class is a higher taxonomic category that can include multiple orders. It groups organisms that share certain characteristics.

4. **Common Characteristics**: Different organisms belonging to different orders can be placed in the same class because they exhibit:
- **Morphological Similarities**: These are similarities in the structure and form of organisms. For example, organisms may have similar body plans or features.
- **Reproductive Similarities**: This refers to similarities in reproductive methods or structures. For instance, organisms may reproduce in similar ways or have comparable reproductive organs.

5. **Conclusion**: Therefore, the reason different organisms from various orders are classified into a single class is due to their shared morphological and reproductive characteristics, despite being from different orders.

### Final Answer:
Different organisms belonging to different orders are placed in a single class due to their similar morphological and reproductive characters.
