Expert Answer:
During pollination, the pollens settle on the stigma of the flower. Once of the cells present in the pollen grain starts forming the pollen tube. The pollen tube grows towards the ovary.
The movement of pollen tube towards the ovary is an example of chemical coordination observed in plants.
