define gravitropic movement
Answers
The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. It also directs roots to grow downward in soil, where they can reach out to take up the water and mineral ions required for plant growth and development.
Gravitropism has an important impact on agriculture. It allows plants to compete for the limited resources available in their immediate environment and ensures that crop shoots resume upward growth after prostration by the action of wind and rain (Fig.1). Consequently, plants can keep their seeds away from soil moisture and pathogens and are more amenable to mechanical harvesting.

________________________________
⇒ what is Gravitropic movment :-
Gravitropic movement is the process in which , roots of the plants grows towards the Gravity.Typically the roots of the plants are growing down into the ground , and leaves and fruits , branches of plants are growing above the place of ground. means growth of the plants gives his opposite response to the gravity .
It is the process of different growth of plants and fungus trees , generally it is a future of many plants as well as some other organisms . that gravity pullings on growth of plant.
