Answer:
-Makes roots to grow downwards in soil
-Allows root to anchor the plant in soil and to absorb the maximum amount of water and minerals from the soil.

Gravitropism is the growth movement in response to gravity. It allows the roots of the plants to grow downwards in the soil. The growth of roots in soil help to anchor the plant to the substratum. It also makes roots to grow deep down in the soil to absorb the maximum amount of water and minerals to support growth and development of the plant.
