plant fertilization is the joining of male and female gametes, resulting in a zygote. The most generalized form of this process requires four steps: pollination, germination, penetration of the ovule, and fertilization. Afterfertilization, the zygote divides to form an embryo.

As the pollen tube penetrates the ovule, it releases two sperm cells. One fuses with the egg to create a diploid zygote, while the other joins with the fusion nucleus to form a triploid nucleus. ... But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.
