1. At what stage does the diploid zygote form?
b. At fertilization. The diploid zygote forms after the pollen tube has finished forming, so that
the male generative nuclei can fuse with the female gametophyte.
2. If a flower lacked a megasporangium, what type of gamete would not form? If the flower
lacked a microsporangium, what type of gamete would not form?
Without a megasporangium, an egg would not form; without a microsporangium, pollen would
not form.
