ICSE Class 10 Answered

what is the role of Auxin in geotropism ?
Asked by Farheen1447 | 19 Feb, 2019, 01:25: AM
answered-by-expert Expert Answer
Auxins help in bending the shoot upwards and downwards due to gravity which shows negative geotropism and positive geotropism. 
If a shoot is placed horizontally in the absence of light, auxins accumulate on the lower side of the shoot, due to gravity; the shoot bends upwards whereas if a root is placed horizontally in the absence of light,auxins accumulate on the lower side of the shoot, due to gravity; the shoot bends downwards.
