In angiosperm, characters of flowers are used in classification because :

Options

A. Characters of flowers are conservative
B. Flowers are large
C. Flowers are attractive
D. None of the above

Answer

To solve the question regarding the classification of angiosperms based on flower characteristics, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Angiosperms**:
- Angiosperms are flowering plants that reproduce through flowers. This distinguishes them from gymnosperms, which are known as naked seed plants.

2. **Importance of Flower Characteristics**:
- Flower characteristics are crucial for classification because they provide consistent traits that can be used to differentiate between various species.

3. **Conservativeness of Flower Characters**:
- Flower characters are considered conservative, meaning they do not change easily and are less influenced by environmental factors compared to vegetative characters (like leaves and stems).

4. **Variation in Vegetative Characters**:
- Vegetative characters can vary widely due to environmental influences, making them less reliable for classification purposes. This variability can lead to difficulties in accurately classifying plants based on these traits.

5. **Conclusion**:
- Given that flower characteristics are more stable and reliable for classification, the correct answer to the question is that the characters of flowers are conservative.

### Final Answer:
- The characters of flowers are used in classification because they are conservative.
