3.4 Seed and Fruit Formation

- the pollen that lands on the stigma grows a pollen tube down to the ovules
- the pollen (male nucleus) travels down the tube to join with an ovule

Formations
1. Pollen nucleus fertilises with the ovule
    --> forms Zygote/Embryo

2. Outside of ovule forms a seed coat

3. Cotyledons form - food source of seedling

4. Thickening of ovary --> fruit  (sugar + protein)
