3.4: Understand that the Growth of the Pollen Tube followed by Fertilisation Leads to Seed and Fruit Formation

SEED AND FRUIT FORMATION

Diagram showing Structure of Flower

EXPLANATION: Pollination involves the transfer of Pollen grain from an Anther (male plant structure) to a Stigma (female plant structure) Hence, when Pollen grain lands on Stigma, this causes a Pollen tube to grow down the Style until it reaches an Ovule within the Ovary This allows the Nucleus of Pollen grain to pass along the Pollen tube to fuse with Nucleus of Ovule via fertilisation As a result, Ovule will form a Seed, while Ovule wall forms the Seed coat, and the rest of Carpel will develop into a Fruit to carry the Seed
