Place the stages in the process of angiosperm pollination in the correct order, beginning with the formation of pollen grains and ending with fertilization. Incorrect Pollen grains form A pollen tube grows from the pollen grain. Pollen is carried away by wind or by animals. The pollen tube reaches the ovary, and two sperm nuclei travel down the pollen tube. Pollen adheres to the sticky end of a stigma. The pollen tube extends down through the style. Fertilization takes place Answer Bank
