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: -The movement of the plant towards the response of gravity pull is known as geotropism. THe roots of the plant show positive stimuli as they grow in the direction of gravity and the stem reflects negative stimuli as it grows in the opposite direction.
Detailed explanation-3: -Gravitropism is the ability of plants to perceive and respond to the gravity vector and orient themselves accordingly. The gravitropic pathway can be divided into three main components: perception, biochemical signaling, and differential growth.
Detailed explanation-4: -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-5: -The growth of the parts of plants in response to the force of gravity is called geotropism.
