Sapling Learning Place the stages in the process of angiosperm pollination in the correct order beginning with the formation of pollen and ending with fertilization. Pollen grains form Fertilization takes place Pollen is carried away by wind or by anigas Pollen adheres to the sticky end of a stigma. The pollen grain grows a pollen tube. The pollen tube extends down through the style. The pollen tube reaches the ovary, and two sperm nuclei travel down the pollen tube Previous Map Solution Fertilization in angiosperms is a critical event. The presence of flowers and sexual organs in these plants make it possible for them to undergo sexual reproduction and thus generate genetic variation. The male counterpart of angiosperm gametophyte are called the pollen and the female counterpart is called the ovum. Generally, the pollen becomes motile with wind.The egg is carried in the female gametangi which has three parts, the uppermost stigma where the pollen attaches, the tubular style through which the pollen moves downwards and the lowermost ovary in which the egg is contained and fertilization takes place. Thus, the correct sequence of events can be found as below: Thus, after fertilization the ovary ripes/matures and becomes the fruit whereas the fertilized egg make up the seeds..
