Botany - Sexual Reproduction in Flowering Plants Question with Solution | TestHub

Double fertilization is characteristic of angiosperms, and it involves syngamy and triple fusion. The fusion of one male gamete with an egg cell is called syngamy, and it results in the formation of diploid zygote. The fusion of second male gamete with a secondary nucleus is called triple fusion, and it results in the formation of triploid primary endosperm nucleus. Double fertilization also increases the viability of the seeds and allows the utilization of both the male gametes produced by the pollen grains.
