Which of the following systems, plants are classified in geneological order :-

Options

A. Artificial
B. Natural
C. Phylogenetic
D. Nonphylogenetic

Answer

To solve the question regarding which system classifies plants in genealogical order, we will analyze the different classification systems mentioned in the question. Here’s a step-by-step solution:

### Step 1: Understand the Classification Systems
- **Artificial System**: This system classifies organisms based on observable characteristics, such as morphology and habits, without considering evolutionary relationships.

- **Natural System**: This system uses a broader range of characteristics, including morphology, anatomy, and physiology, to classify organisms based on their natural relationships.

- **Phylogenetic System**: This classification is based on the evolutionary relationships and ancestral lineages of organisms. It considers how species have evolved over time and their common ancestry.

- **Non-Phylogenetic System**: This term is not commonly used in biological classification and generally refers to systems that do not consider evolutionary relationships.

### Step 2: Identify the Key Concept
- The question specifically asks for the system that classifies plants in genealogical order. Genealogy refers to the study of ancestral relationships and lineages.

### Step 3: Analyze the Options
- **Artificial System**: Not genealogical; based on observable traits.
- **Natural System**: More comprehensive but not strictly genealogical.
- **Phylogenetic System**: Directly relates to genealogical order as it focuses on evolutionary relationships and ancestry.
- **Non-Phylogenetic System**: Not applicable as it does not focus on genealogy.

### Step 4: Conclusion
- Based on the definitions and characteristics of the classification systems, the correct answer is the **Phylogenetic System**. This system classifies plants based on their evolutionary history and genealogical relationships.

### Final Answer
- The system in which plants are classified in genealogical order is the **Phylogenetic System**.
