HORTICULTURE

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: -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.

Detailed explanation-3: -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-4: -Geotropism is a similar occurrence to phototropism where the plant exhibits directional growth in response to gravity. The shoot tip illustrates negative geotropism (grows against the force of gravity) while the root tip exhibits positive geotropism (grows in the same direction as gravity).

Detailed explanation-5: -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.
