Understanding Anatropous Ovules
Anatropous ovules are a specific type of ovule found in flowering plants, characterized by their unique orientation and attachment to the ovary.
Funicle and Ovary Connection
In anatropous ovules, the funicle (the stalk connecting the ovule to the ovary) is:
- Fused with the ovary.
- This fusion occurs at a specific point, allowing for effective nutrient transfer during the development of the ovule.
Importance of Fusion
The fusion between the funicle and the ovary serves several critical functions:
- Nourishment: It facilitates the transfer of nutrients and support from the ovary to the developing ovule.
- Stability: The fused connection helps stabilize the ovule in its position within the ovary, ensuring proper development.
- Efficient Development: This relationship allows the ovule to receive necessary resources during its growth phase, leading to the formation of seeds post-fertilization.
Comparison with Other Ovule Types
In contrast to anatropous ovules, other types, such as orthotropous and campylotropous ovules, display different orientations and connections:
- Orthotropous: Funicle is typically detached.
- Campylotropous: The funicle may be bent but is not fused in the same manner as in anatropous ovules.
Conclusion
The correct answer is option 'B' because the funicle in anatropous ovules is indeed fused with the ovary, playing a vital role in the plant reproductive process by ensuring the ovule's proper development and nourishment.
