Detailed explanation-1: -Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it.

Detailed explanation-2: -Explain to students that plants respond to different forces; sunflowers follow the light, pea tendrils grasp whatever they touch, and plants respond to gravity. This response to gravity is called Geotropism. Geotropism causes roots to grow downward, and stems and leaves to grow up.

Detailed explanation-3: -Plants responses to gravity: when the stem grows against the force of gravity, this is known as a negative geotropism. when a root grows in the direction of the force of gravity, this is known as a positive geotropism.
