Geotropism
Gravity affects the root growth by a mechanism called gravitropism.

A root's downward growth as a response to gravity is called positive gravitropism or positive geotropism.

Geotropism
Gravitropism, which is a growth movement by a plant, fungus, or animal in response to gravity. Charles Darwin was one of the first to scientifically document this.
The roots of a plant grow downward in response to gravity. This is called positive gravitropism or positive geotropism. Roots grow toward the pull of gravity while shoots grow away from the force of gravity.
Geotropism is a plant growth or movement in response to gravity. Upward growth of the plant's parts against gravity is called negative geotropism, whilst downward growth of roots is called positive geotropism.
Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.

A tropism is a growth response whose direction is determined by the direction of the stimulus. Growth towards the stimulus is called a positive tropism. Growth away from the stimulus is called a negative tropism. The response to light is called phototropism. Shoots are positively phototropic, roots are negatively phototropic. The response to gravity is called gravitropism (or sometimes geotropism). Shoots are negatively gravitropic and roots are positively gravitropic. http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/T/Tropisms.html
