BIOMOLECULES AND ENZYMES

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. It also occurs in fungi. Gravity can be either “artificial gravity” or natural gravity.

Detailed explanation-2: -Gravitropisms. Phototropism is a response to the stimulus of light, whereas gravitropism (also called geotropism) is a response to the stimulus of gravity . When the stem grows against the force of gravity (upwards), this is known as a negative gravitropism.

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. Among the first scientists to study geotropism was Charles Darwin.

Detailed explanation-4: -Geotropism is a similar occurrence to phototropism where the plant exhibits directional growth in response to gravity.

Detailed explanation-5: -If the movement of the plant parts is towards the pull of gravity, it is known as positive geotropism; whereas if the movement of the plant parts is in the direction opposite to the pull of gravity, it is known as negative geotropism. The movement of roots towards the soil is an example of positive geotropism.
