Triple fusion in plants
Triple fusion in plants involves the fusion of the second male gamete with two polar nuclei. This process is essential for the formation of endosperm in angiosperms.
Process of triple fusion
- After the pollen grain lands on the stigma, it germinates and forms a pollen tube.
- The generative cell in the pollen tube divides to form two sperm cells.
- One sperm cell fuses with the egg cell to form a zygote, while the other sperm cell undergoes triple fusion.
- The second sperm cell fuses with two polar nuclei present in the central cell of the embryo sac.
- This fusion results in the formation of the triploid primary endosperm nucleus (3n).
- The primary endosperm nucleus undergoes multiple divisions to form the endosperm, which provides nourishment to the developing embryo.
Significance of triple fusion
- Triple fusion is crucial for seed development in plants as it leads to the formation of endosperm, which provides nutrients to the growing embryo.
- Endosperm acts as a storage tissue rich in nutrients like starch, proteins, and lipids, essential for the growth and development of the embryo.
In conclusion, triple fusion plays a vital role in plant reproduction by ensuring the formation of endosperm, which supports the growth of the developing embryo.
