The observation that provides evidence of gravitropism is:
Seedlings planted in containers that are tipped over sideways extend their roots downward.
Gravitropism (also known as geotropism) is the directional growth of an organism in response to gravity. Roots typically exhibit positive gravitropism by growing downward, while stems exhibit negative gravitropism by growing upward.
