3.4 fertilization

pollen grains germinate and a tube begins to grow down the stigma and connects to the ovule
pollen grains(containing male nucleus)  move down the pollen tube into ovule
1.pollen nucleus then fertilizes the ovule
this makes a zygote
which then grows into  the embrionic plant
2.outside ovule forms the TESTA or the seed coat
3.inside ovule forms cotyleton's-->food stores for seed
4. thickening of ovary walls--> fruit
