Answer: it grows a tube to travel down to the ovary
Explanation:
As a result of pollination, pollen grain lands on the sigma of the pistil or carpel. On the stigma pollen grain begins to germinate and grows a long pollen tube. The pollen tube grows longer and makes its way from the stigma, down the style and reaches to the ovary. Pollen tube carries two male gametes or sex cells. One male gamete fertilize the egg cell to produce zygote and the gamete fuses with polar nuclei to form primary endosperm cell.
Ex: Draw the United States, then draw a transform plate boundary starting in the middle of California down into the ocean.
<span>The Galapagos Islands are geographically isolated due to the Ocean that surrounds the islands themselves. The finches can't fly far enough to make it past the vast ocean to other mainland so they are stuck on the island and must adapt to what the island provides for food in varying areas.</span>
