Notes
Fertilisation
- Germinate (tube grows downward)
- Species specific, only same pollen can germinate
- Pollen ----- pollen tube (style) ---> Ovule
Formation of seed
1. Fertilisation
Pollen nucleus + Ovule -------> Zygote -----> Embryonic Plant
2. Coating
Outside ovule forms seed coat (TESTA)
3. Food Store
Cotyledons (along with Zygote) - food stores to support plant
4. Fruit
Ovary walls thicken (energy used - sugars/proteins) ----> Fruit

ReplyDeleteNice work. We will take a look at seeds and fruit in the next lab. A chance to capture images and apply your knowledge.
