the most common type of ovule is

Options

A. Orthotropous
B. Hemitropous
C. Antraopous
D. Campylotropous.

Answer

To determine the most common type of ovule, we need to analyze the different types of ovules based on their orientation. Here’s a step-by-step solution:

### Step 1: Understand the Types of Ovules
There are several types of ovules classified based on their orientation:
- **Orthotropous**: The ovule is straight and the micropyle, chalaza, and funicle are aligned (0 degrees).
- **Hemitropous**: The ovule is bent at an angle of 90 degrees.
- **Anatropous**: The ovule is inverted or rotated 180 degrees.
- **Campylotropous**: The ovule is curved, with the funicle being extended.

### Step 2: Identify the Most Common Type
Among these types, the **Anatropous** ovule is the most commonly found type. In this orientation, the ovule is rotated such that the micropyle is positioned close to the funicle, making it a prevalent form in many flowering plants.

### Step 3: Conclusion
Based on the analysis, the most common type of ovule is **Anatropous**. Therefore, the correct answer to the question is **Option 3: Anatropous**.
