Fruit + Seeds / Dissection of an Apple

- After the seeds have fertilized, they either become a seed pod or a fruit in order to reproduce.

 Dissection of an Apple:

- Apples are the colour red because of the need to attract animals. 

Animal eats the apple --> The seed remains in the animals system --> The animal "does its business" and inside the poo lies the seed --> The seed starts to grown again after some time.

 Example of Seed Pods:

 Example of Fruits:

2.80 Geotropism

- Geo = gravity, tropic = growth response
- An example: seed:
- the embryonic roots grow downwards, this is described as positive geotropism
- the embryonic shoot will grow upwards, this is negative geotropism

- Further experiment: take the same germinating seed and rotating it anti-clockwise to face upwards.
- The shoot grow upwards showing negative geotropism
- The roots will grow downwards showing positive geotropism
