In flowering plants, sexual reproduction involves the fusion of male and female gametes (sperm and ovule). The process begins with pollination, where pollen from the male part (anther) reaches the female part (stigma). The sperm cells then travel through the style to fertilize the ovule in the ovary. After fertilization, the ovule develops into a seed, and the ovary forms the fruit.
