Triple Fusion in Flowering Plants — NEET Biology
📚 Practice ConceptWhat is triple fusion? Where and how does it take place? Name the nuclei involved in triple fusion.
Which of the following statements are correct regarding sexual reproduction in angiosperms? S1: The generative cell divides to form two male gametes either before pollen shedding or during pollen tube growth in the pistil. S2: The filiform apparatus guides the pollen tube directly into the egg cell, where male gametes are discharged. S3: Syngamy is the fusion of one male gamete with the egg cell, forming a diploid zygote. S4: Triple fusion involves the fusion of the second male gamete with the two polar nuclei, forming a triploid Primary Endosperm Nucleus (PEN). S5: The endosperm tissue is always completely consumed by the developing embryo before seed maturation in all angiosperms. S6: Double fertilisation, an event unique to flowering plants, consists of syngamy and triple fusion.
