Detailed explanation-1: -Geotropism is a type of tropism where plants show some growth in response to gravity. Roots growing downwards is an example of geotropism.
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: -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-4: -Geotropism is growth movement by a plant in response to gravity (e.g. most of the roots grow downwards).
Detailed explanation-5: -It is a tropic movement in response to gravity. It is also called gravitropism. Positive geotropism occurs when plant organs develop in the direction of gravity. Example-The growth of roots towards gravity.
