ZIMSEC O Level Combined Science Notes: Reproduction in plants: The fertilization process

  • After a flower has been pollinated, pollen grains grow down the stigma
  • The pollen grains germinate
  • They grow through the style towards the ovary
  • Inside the ovary are the ovules which each contain an egg cell
  • The pollen tube carries the male nucleus down into the ovule
  • Fertilisation is the union (/joining together) of the male and female nuclei
  • It takes place inside the ovules
  • It is important to note that not every pollen grain germinates and not every ovary develops into a seed.
