(I)GCSE Topic 3.4 Plant Fertilisation

-When the pollen grain lands on the Stigma, it travels down the pollen tube and enters the ovule.
-When the pollen grain fertilises with the ovule;
- Zygote will form and later the Zygotes will later divide and turn into an embryo.
- Seed coat called the Testa will form outside of the ovule.
- Cotyledons form inside the ovary, the Cotyledons store food for the seedlings.
- The wall of the ovary thickens because it starts to store foods such as protein, sugars etc. and starts to form a fruit.
