Which of the following systems of classification involves usage of one or few morphological characters for grouping of organisms ?

Options

A. Artificial system
B. Natural system
C. Phylogenetic system
D. Bentham & Hooker's system

Answer

To solve the question "Which of the following systems of classification involves usage of one or few morphological characters for grouping of organisms?", we will analyze the options provided and identify the correct answer step by step.

### Step 1: Understand the Question
The question is asking about a classification system that uses one or a few morphological characters to group organisms. Morphological characters refer to the physical traits or structures of organisms.

### Step 2: Analyze the Options
The options given are:
1. Artificial system
2. Natural system
3. Phylogenetic system
4. Bentham and Hooker's system

### Step 3: Evaluate Each Option
- **Artificial System**: This system, proposed by Carolus Linnaeus, classifies organisms based on a limited number of morphological traits, such as the number and arrangement of reproductive structures (like stamens and styles). It does not consider evolutionary relationships.

- **Natural System**: This system, also known as Bentham and Hooker's system, classifies organisms based on their natural affinities and overall similarities in morphology, rather than just a few traits. It considers a broader range of characteristics.

- **Phylogenetic System**: This classification system is based on the evolutionary and genetic relationships among organisms. It looks at ancestral and derived traits, which is more complex than just a few morphological characters.

- **Bentham and Hooker's System**: As mentioned, this is synonymous with the natural system of classification and focuses on natural affinities rather than just a few traits.

### Step 4: Identify the Correct Answer
Based on the analysis, the **Artificial System** is the correct answer as it relies on a limited number of morphological characters for classification.

### Final Answer
The correct option for this question is **Artificial System**.
