“At the micropylar end where the pollen tube delivers the two sperm cells, the egg cell is flanked by two synergids that assist in fertilization.”

“The activities of both enzymes increase in a similar temporal manner in the micropylar and lateral endosperm during and following germination.”

“Most globular pro-embryos were located at the micropylar end between the central cell with unfused neighboring polar nuclei and intact synergid cells.”
