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: -This response to gravity is called Geotropism. Geotropism causes roots to grow downward, and stems and leaves to grow up.

Detailed explanation-3: -An example of plants responding to gravity is the fact that roots grow towards the earth and shoots grow away from the earth. This bidirectional growth is influenced by gravity, and is therefore called gravitropism.

Detailed explanation-4: -The growth of plant roots is an example of geotropism as it grows towards the direction of gravity.

Detailed explanation-5: -Gravitropism (also known as geotropism) is a coordinated process of differential growth by a plant in response to gravity pulling on it.
