Ovules in pinus are generally

Options

A. Anatropous with four integuments
B. Anatropous with one integument
C. Amphitropous with three integuments
D. Orthotropous with two integuments

Answer

To determine the general characteristics of ovules in Pinus, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Types of Ovules**:
- Ovules can be classified based on their orientation and the number of integuments. Common types include anatropous, orthotropous, and others.

2. **Analyzing the Options**:
- **Option 1**: Anatropos with four integuments.
- This option is incorrect because ovules in Pinus are not characterized by four integuments; they typically have one.

- **Option 2**: Anatropos with one integument.
- This option is correct. In Pinus, the ovules are anatropous, meaning they are inverted and have one integument.

- **Option 3**: Orthotropos with two integuments.
- This option is also incorrect. Orthotropous ovules are straight and have a micropyle at the apex, which does not describe the ovules in Pinus.

3. **Conclusion**:
- Based on the analysis of the options, the correct answer is that ovules in Pinus are generally **anatropos with one integument**.

### Final Answer:
The correct answer is **Option 2: Anatropos with one integument**.
