2.80 Geotropism

- Geotropic. Geo = Gravity. Tropic = Growth response 
- Embryonic root grows downwards in a seed (Positive Geotropism) 
- It SHOULD grow upwards (Negative geotropism) 
- If you take the same seed but rotated the shoot then grows upwards (Negative) and the Embryonic root will grow downwards (Positive)
