3.4 Plant Fertilisation: Understand that the growth of the pollen tube followed by fertilization leads to seed and fruit formations.

• Pollen grains (on stigma) they germinate. 
• The pollen tubes the nuclease travels down into the ovule. In other words pollen nuclease will fertilized the ovule which will form zygote which will grow into the abronia plant. 
• Outside of the ovule forms the seed coat which is call TESTA.
• Inside of the ovule we also cotyledons which stored food for the seedings. 
• The thickening of the wall which protects the ovary where the plants will put a lot of energy such as sugar, protein and built this up and this will form the fruit which is develop from the wall of the ovary or the carpal.
