Figure At what stage does the diploid zygote form?

  1. when the female cone begins to bud from the tree
  2. at fertilization
  3. when the seeds drop from the tree
  4. when the pollen tube begins to grow

Hint:

Figure B. The diploid zygote forms after the pollen tube has finished forming, so that the male generative nuclei can fuse with the female gametophyte.
