- Geo tropic refers to growth responses as a result of gravity.
- An example of this is when in a seed the root grows downwards, this is positive geotropism. Whereas if it grows upwards towards the surface it is negative geotropism.
- If the seed turns for example 90 degrees, the roots will adjust the direction of growth again either towards the surface (negative geotropism) or downwards (positive geotropism).
