Gravitropism orients the roots in a downward direction to better serve the purpose of anchorage and water uptake.

Gravitropism directs the roots to the best underground water supply.

Detailed explanation-1: -Gravitropism is an integral part of plant growth, orienting its position to maximize contact with sunlight, as well as ensuring that the roots are growing in the correct direction. Growth due to gravitropism is mediated by changes in concentration of the plant hormone auxin within plant cells.
Detailed explanation-2: -Plants are capable of orienting their root growth towards gravity in a process termed gravitropism, which is necessary for roots to grow into soil, for water and nutrient acquisition and to anchor plants.
Detailed explanation-3: -It is essential for roots to grow down so they can explore the soil and maximise their water uptake.
Detailed explanation-4: -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-5: -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.
