This is Nadine and Peter. They have temporarily taken the place of the donkey and bird, who are off sick. They explain germination.

| What is germination, Peter? My teacher told me that it's how a baby plant grows. | |
 | |  |
|
 |
| | |
| That's right, to some extent. Germination is the process by which the embryo plant in the seed grows until it can photosynthesize by itself. | |
| | |
|
|
|
|
And what makes germination possible? The weather?
|
|
|
|
| | |
| It isn't the weather that dictates how well germination will occur - well, not really. It needs certain things to happen. | |
| | |
|
|
| | |
| OH YES! I know this!! It needs warmth, water and oxygen. Warmth for enzyme efficiency, water to soften the testa and for chemical reactions and oxygen for respiration (and energy)! | |

| | |
| Exactly! Well done, Peter. Did you know, the radicle's growth downwards is called positive geotropism? | |
| | |
|
|
| | |
| Oh yeah, and I heard that growing upwards (like the plumule) is negative geotropism. That must mean that geotropism is growing towards the earth, which the root does and shoot doesn't! | |
