The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks about the type of ovules found in Capsella (shepherd's purse) and Pisum sativum (pea plant). 2. **Identifying the Type of Ovule**: The ovules of both Capsella and Pisum sativum are classified as "camphylotropus" type ovules. 3. **Characteristics of Camphylotropus Ovule**: - **Curved Structure**: The camphylotropus ovule is characterized by its curved shape. - **Micro Pile Position**: In this type of ovule, the micropyle (the opening through which the pollen enters) is positioned very close to the funiculus (the stalk that attaches the ovule to the ovary). - **Embryo Sac Location**: The embryo sac, which contains the female gametes, is located in the middle of the ovule. 4. **Visual Representation**: Imagine the ovule as a curved structure where the micropyle is almost touching the funiculus. This curvature is a distinctive feature of the camphylotropus ovule. 5. **Conclusion**: Therefore, the ovules of Capsella and Pisum sativum are examples of camphylotropus type ovules.
