Percentage sign(%) is used for

Options

A. actinomorphic flower
B. zygomorphic flower
C. incomplete flower
D. epigynous flower

Answer

To solve the question regarding the use of the percentage sign (%), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks what the percentage sign (%) represents in the context of flowering plants. The options provided are:
- A) Actinomorphic class
- B) Zygomorphic class
- C) Incomplete class
- D) Epigenesis class

2. **Identifying Key Terms**: We need to focus on the terms "actinomorphic" and "zygomorphic," as these relate to the symmetry of flowers.

3. **Defining Actinomorphic Flowers**: Actinomorphic flowers exhibit radial symmetry. This means that they can be divided into two equal halves by multiple planes that pass through the center. Examples include mustard and datura.

4. **Defining Zygomorphic Flowers**: Zygomorphic flowers exhibit bilateral symmetry. This means they can only be divided into two equal halves by one specific vertical plane. Examples include pea, gulmohar, and bean.

5. **Connecting the Percentage Sign**: The transcript indicates that the percentage sign (%) is used to represent zygomorphic flowers. This is based on the classification of flowers according to their symmetry.

6. **Choosing the Correct Answer**: Since the percentage sign (%) represents zygomorphic flowers, the correct answer to the question is B) Zygomorphic class.

### Final Answer:
The percentage sign (%) is used for **B) Zygomorphic class**.
