Pollination, Fertilisation and Seed: a 3D model for Class 8–10 Science, covering the stamen (anther on a filament) makes pollen; the pistil has a stigma, a style and an ovary that holds ovules, pollination is the transfer of pollen from an anther to a stigma…, pollination comes first; fertilisation happens later, inside the ovule, a pollen grain is not a sperm cell: on the stigma it grows a pollen tube that carries two male gametes, pollen landing on a petal or other non-stigma surface does not grow a tube and leads to no fertilisation.

  • the stamen (anther on a filament) makes pollen; the pistil has a stigma, a style and an ovary that holds ovules
  • pollination is the transfer of pollen from an anther to a stigma…
  • pollination comes first; fertilisation happens later, inside the ovule
  • a pollen grain is not a sperm cell: on the stigma it grows a pollen tube that carries two male gametes
  • pollen landing on a petal or other non-stigma surface does not grow a tube and leads to no fertilisation
  • the pollen tube grows down the style and enters an ovule through a small opening (the micropyle)
  • one male gamete fuses with the egg cell to form a zygote (fertilisation)
  • the other male gamete fuses with the central cell nuclei and starts the endosperm, a food store (double fertilisation…
  • after fertilisation the zygote grows into an embryo and the ovule becomes a seed with a seed coat and stored food
  • the ovary wall grows into the fruit around the seeds; the petals, stamens, style and stigma wither
  • an ovule that is not fertilised does not become a seed
