When ovule is straight so the funiculus, chalaza and micropyle lie in one vertical line, the ovule is said to be ?

Options

A. Anatropous ovule
B. Amphitropous ovule
C. Orthotropous ovule
D. Hemitropous ovule

Answer

To determine the type of ovule when the funiculus, chalaza, and micropyle lie in one vertical line, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Ovule**:
- The ovule consists of several parts: the funiculus (stalk), the chalaza (the base), and the micropyle (the opening).

2. **Identify the Orientation of the Ovule**:
- When the ovule is described as "straight," it indicates that the funiculus, chalaza, and micropyle are aligned vertically.

3. **Classify the Types of Ovules**:
- There are different types of ovules based on their orientation:
- **Orthotropous Ovule**: The funiculus, chalaza, and micropyle are in a straight line.
- **Anatropous Ovule**: The ovule is inverted, bending 180 degrees.
- **Amphitropous Ovule**: The ovule is bent but not inverted.
- **Hemitropous Ovule**: The ovule is bent at a 90-degree angle.
- **Campylotropous Ovule**: The ovule is curved, resembling a horseshoe.
- **Sassinotropous Ovule**: The funiculus is extended, but the structure is not aligned vertically.

4. **Conclusion**:
- Since the question specifies that the funiculus, chalaza, and micropyle are in one vertical line, the correct classification is **Orthotropous Ovule**.

### Final Answer:
The ovule is said to be **Orthotropous Ovule**.
