A scientist plants seedlings in different conditions to demonstrate how plants respond to their environment. Which of these observations provides evidence of gravitropism?(1 point)

Question

Responses

Seedlings planted in containers that are tipped over sideways grow sideways.

Seedlings planted in containers that are tipped over sideways extend their roots downward.

Seedlings planted near a stick wrap around the stick.

Seedlings planted away from a source of sunlight grow toward the light.

Answer 1

The observation that provides evidence of gravitropism is:

Seedlings planted in containers that are tipped over sideways extend their roots downward.

Gravitropism is the growth response of a plant in relation to gravity, where roots grow downward (positive gravitropism) and shoots grow upward (negative gravitropism).
