Natural system of classification differs from artifical system in

Options

A. amploying only one floral trait
B. employing only one vegetative trait
C. bringing out similarities and dissimilarities
D. developing evolutionary trends.

Answer

### Step-by-Step Solution

1. **Understanding Classification Systems**:
- Classification systems are methods used to categorize living organisms. There are two main types: natural and artificial classification systems.

2. **Artificial Classification System**:
- The artificial system of classification, first proposed by Carl Linnaeus, primarily focuses on external morphological traits. This means it classifies organisms based on observable characteristics such as shape, size, color, and structure.
- It does not consider other factors like genetic, biochemical, or ecological relationships. For example, two plants that look similar may be grouped together, even if they are not closely related evolutionarily.

3. **Natural Classification System**:
- In contrast, the natural classification system, developed by botanists like Bentham and Hooker, takes a broader approach. It considers multiple characteristics, including:
- **Morphology**: External features of the organism.
- **Cytology**: The study of cell structure.
- **Phytochemistry**: The chemical composition of the plants.
- **Embryology**: The study of the development of the organism from fertilization to maturity.
- This system aims to reflect the evolutionary relationships and similarities/dissimilarities among organisms, leading to a more accurate grouping based on a comprehensive set of traits.

4. **Key Differences**:
- The main difference lies in the criteria used for classification:
- **Artificial System**: Based solely on external morphology.
- **Natural System**: Based on a wide range of characteristics, including morphology, cytology, phytochemistry, and embryology, which helps in understanding evolutionary trends.

5. **Conclusion**:
- The natural classification system provides a more holistic view of the relationships between organisms, while the artificial system is limited and may not accurately reflect these relationships.
