2.80 Geotropism

- GEO--TROPIC
geo --> gravity
tropic --> growth response
GEOTROPIC ---> growth response to gravity
- positive geotropism --> when an embryonic root grows downwards it is described as positive geotropism
- negative geotropism --> when an embryonic shoot grows it grow upwards this is described as negative geotropism
- even if the seed is flipped around the embryonic shoot would still find its way to grow upwards showing negative geotropism and the embryonic root would find its way to grow downwards showing positive geotropism.
