Horizontally oriented ovule in Angiouperm is called

Options

A. Amphitropous
B. Hemitropous
C. Campylotropous
D. Circinotropous

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for the term used to describe a horizontally oriented ovule in angiosperms.

2. **Identifying Types of Ovules:**
There are six types of ovules in angiosperms:
- Anatropous
- Orthotropous
- Hemitropous
- Campylotropous
- Amphitropous
- Circinotropous

3. **Analyzing the Options:**
We need to analyze the given options:
- **Amphitropous:** The curvature of the ovule is pronounced, but it is not horizontally oriented.
- **Hemitropous:** The body of the ovule is placed transversely at a right angle, which indicates a horizontal orientation.
- **Campylotropous:** The ovule is curved, and the micropyle and chalaza do not line up straight, which does not indicate horizontal orientation.
- **Circinotropous:** The ovule starts straight but becomes anatropous due to growth, which does not indicate horizontal orientation.

4. **Determining the Correct Answer:**
Based on the analysis, the only option that describes a horizontally oriented ovule is **Hemitropous**.

5. **Conclusion:**
Therefore, the correct answer to the question is **Hemitropous**.
