Yes, geotropism DOES determine the direction of growth. Negative geotropism is when a section of the plant grows upwards. For example, stems grow upward. Positive geotropism is when a section of the plant grows downwards. In this case, a plant's roots would be the perfect example.
Geotropism is the response to gravity, not depending on how fast the root grows. Geotropism is only determining the direction of growth.
Auxins promote growth in stems, making them grow upwards.
Auxins inhibit growth in roots, making them grow downwards.
stems and leaves exhibit negative 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
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
Gravitropism is a response to gravity. And the plant roots will follow the gravity also you cannot change the place where the roots will grow also if you will put it on the opposite side of the gravity it will also grow down.
A change in plant growth due to gravity is gravitropism. Roots have a tendency to grow in the direction of strongest gravitational pull.

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.
It is called geotropism.
By geotropism and presence of moisture in the soil roots determine their way for growth.
light, positive phototropism and towards the light gravity, negative geotropism and grow in opposite direction to gravity NOT WATER

firstly there is no word as GVRAVITROPISM. When plants grow towards gravity it is called GEOTROPISM. its is mainly the root of plants that show geotropism; because they grow downward. but the stem show negative geotropism because it grows up in the opposite direction of gravity
