What is the significance of double fertilization?

Double fertilization is significant for several reasons:

1. Efficient Resource Utilization: It ensures that the endosperm, which provides nourishment to the developing embryo, is only formed if the egg is fertilized. This prevents the plant from wasting resources.
2. Genetic Variation: The formation of both a zygote and endosperm contributes to genetic diversity, which is beneficial for the adaptability and survival of the plant species.
3. Seed Development: The process is crucial for the proper development of seeds, which are vital for the propagation of flowering plants.

Overall, double fertilization is a highly efficient and evolutionary advantageous mechanism in angiosperms.
