Detailed explanation-1: -Gravitropism is the ability of plants to perceive and respond to the gravity vector and orient themselves accordingly.

Detailed explanation-2: -Geotropism (also called gravitropism) is the directional growth of an organism in response to gravity. Roots display positive geotropism when they grow downward, while shoots display negative geotropism when they grow upward.

Detailed explanation-3: -The movement of plant parts in response to the direction of gravity is known as geotropism. The growth of plant roots is an example of geotropism as it grows towards the direction of gravity.

Detailed explanation-4: -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.
