Double fertilization is a distinctive process in flowering plants where one male gamete fertilizes the egg, forming a zygote, and another male gamete fuses with the polar nuclei to produce the triploid endosperm. 1. Efficient Resource Utilization: Guarantees that the endosperm, the embryo’s nutritional source, develops only after successful fertilization. 2. Simultaneous Development of Two Structures: Results in the concurrent formation of both the zygote (embryo) and the endosperm. 3. Enhanced Seed Viability: Promotes better nutrition and increased survival prospects for the embryo. 4. Triploid Endosperm Production: Acts as a vital food reserve, supporting the seedling’s initial growth.
