Answer 2

$\textbf{Geotropism}$:

It refers to the tropic response of organism to gravity.

Like, growth of root of a plant is because of the geotropism.

Positive geotropism is observed when growth of plant part is towards the stimulated stimuli like growth of root. Whereas, negative geotropism is observed when plant part responds in different direction of generated stimuli like, growth of stem.
