The correct sequence of processes that takes place when a flowering plant reproduces is first meiosis which produces haploid (n) gametes, then pollination which transfers the male gametes (pollen) to the female reproductive structure (stigma), then nuclear fusion occurs between the male and female gametes resulting in a diploid (2n) zygote, and lastly, the formation of embryo and endosperm takes place where the zygote undergoes mitosis and cell differentiation to form the embryo and the endosperm, which provides nutrients for the developing embryo. The growth of the pollen tube is not a main process involved in reproduction, but rather a mechanism for delivering the male gametes to the female reproductive structure.
