On which of the following is the artificial system of classification based?

Options

A. Habit, colour, number and shape of leaves
B. Androecium structure
C. Cytological information such as chromosome number structure
D. Both (A) and (B)

Answer

To solve the question regarding the basis of the artificial system of classification, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Artificial Classification**:
- The artificial system of classification organizes organisms based on observable characteristics rather than evolutionary relationships. This means it does not consider the ancestry or evolutionary lineage of the organisms.

2. **Identifying Characteristics Used in Artificial Classification**:
- The characteristics typically used in artificial classification include:
- Habit (growth form)
- Color
- Number of leaves
- Shape of leaves

3. **Evaluating the Options**:
- The question provides several options to choose from. We need to evaluate each option based on whether it aligns with the characteristics used in artificial classification.
- **Option A**: Habit, Color, Number, and Shape of Leaves - This is correct as these are observable traits.
- **Option B**: Androsium Structure - This is also correct as it refers to the reproductive structure of plants, which can be used for classification.
- **Option C**: Cytological Information (such as chromosome number) - This is incorrect for artificial classification as it involves evolutionary relationships.

4. **Conclusion**:
- The artificial system of classification is based on observable traits such as habit, color, number, and shape of leaves, as well as androsium structure. Therefore, the correct answer would be the combination of options that include these characteristics.

### Final Answer:
The artificial system of classification is based on:
- Habit, Color, Number, and Shape of Leaves (Option A)
- Androsium Structure (Option B)
