Explanation:
Pseudogamous Endosperm Development:
- In apomicts where the embryo develops parthenogenetically, the polar nuclei get fertilized and produce endosperm.
- This type of endosperm development is called pseudogamous.
Definition of Pseudogamous:
- Pseudogamous endosperm development refers to the fertilization of the polar nuclei within the embryo sac, resulting in the formation of endosperm without the fusion of gametes.
Characteristics of Pseudogamous Endosperm:
- Pseudogamous endosperm development involves the fusion of a sperm cell with the polar nuclei in the embryo sac.
- This process leads to the formation of endosperm that is genetically similar to the embryo.
Significance of Pseudogamous Endosperm:
- Pseudogamous endosperm plays a crucial role in the development of seeds in apomictic plants.
- It provides necessary nutrients and support for the developing embryo, ensuring successful seed development.
Conclusion:
- Pseudogamous endosperm development is a unique process observed in apomictic plants where the polar nuclei get fertilized to produce endosperm without the fusion of gametes.
