3.4 PLant fertlisation

• pollen grains grow all the way down the stigma, making a pollen tube
• the nucleus travels down the tube and into the ovule

A number of things will occur:
1. Ovule will fertilise that leads to formation of zygote that grows into a embrionic plant
2. Oustide of the ovule: seed coat (TESTA)
3. Formation of cotyletons (food stores for seedling)
4. Thickning of the walls of the ovary, putting things like sugar, protein that will create fruit
