3.4 Plant fertilisation
Understand that the growth of the pollen tube followed by fertilisation leads to seed and fruit formation
The pollen grains (on the stigma) germinate and a tube known as the pollen tube grows descending down to the ovule. (The male nucleus travels down there into the ovule)
1.(Fertilisation) Pollen nucleus fertilises the ovule, this forms a
ZYGOTE which grows to become an embryonic plant.
nice diagram. In the lesson this week you can add images of fruits and seeds.
