Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.
<h3>What is negative gravitropism?</h3>
Negative gravitropism occurs when shoots develop in the opposite direction of gravity toward sunlight.
Plants respond immediately to the gravitational attraction of the Earth as well as to light. Stems develop away from the center of the Earth and toward the light due to negative gravitropism.
Thus, the given experiment shows negative gravitropism.
