Step 1: Understanding Triple fusion.
Triple fusion is a process that occurs during fertilization in angiosperms (flowering plants). It involves the fusion of one male gamete (sperm) with two polar nuclei in the central cell of the embryo sac. This results in the formation of a triploid cell, which develops into the endosperm, providing nutrition to the developing embryo.
Step 2: Conclusion.
Triple fusion plays a crucial role in the formation of the endosperm, which is vital for seed development in plants.
