Answer:
Fertilization Follows. During the spring of the female cone's second year, the male and female gametes are ready. The pollen grows a pollen tube, which enters a little hole in the ovule's skin near its basal end, called the micropyle. The tube enters the ovule, and the sperm goes down the tube and into the ovule.
Once an egg is fertilized by a sperm, a zygote is formed. The zygote divides into multiple cells in a process known as cleavage, triggering the beginning of embryonic differentiation. ...
