First, pollen would be released from the male part of flower (anther) and pollen would be received by the female part (stigma) by either wind or insects.
The pollen will travel down the style, and enter the ovary. The pollen will fuse with the egg and produce a zygote. The zygote will eventually grow into a fruit.
The seed inside the fruit will be released and when it germinates, a new plant is reproduced.
