Answer:
1) Pollen is released from the anther.
2) Pollen sticks to the stigma.
3) Pollen tube forms and grows through the style.
4) The pollen tube reaches the ovule within the ovary.
5) Sperm fertilizes the egg.
Explanation:
Pollination is a process in which pollen grains are transfer from anther to stigma of the flower. It occurs through wind, water and insect such as bees. When pollen gets mature, it falls from anther to the stigma. There it makes a tube which goes to the ovary. This pollen reaches the ovary through this tube and combines with ovule and fertilization occurs.
