- Pollen grain on the stigma and they germinate and tubes begin to grow off them which then enter the ovule. The nucleus moves down the pollen tube to the nucleus
- Pollen nucleus will fertilize the ovule leads to formation of the Zygote (grow in the embryotic plant)
- Outside of the ovule forms the seed coat called the TESTA
- Also inside the Ovule are the Cotyledons which are food stores for the seedlings. This will support the plant until it has developed its first leafs
- Thickening of the walls of the ovaries. The plant will put in a lot of energy, things like sugars/proteins. Build up will create fruits (developed in the wall of the ovary/carpel)
