The roots are attracted to moisture in the soil
downwards or in the direction of gravity.
Gravity affects the growth of plants as well as their height, and that is why roots will always grow downwards into the soil, while heavy branches will always tend to bend downwards.
Positive gravitropism is the growth movement of a plant towards the gravity source, like roots growing downwards, while negative gravitropism is the growth movement away from the gravity source, like stems growing upwards. Both responses help plants optimize their growth in relation to gravity.

Gravity. Gravitropism is when an object either moves towards or away from the force of gravity
Plants have specialized cells in their roots called root hairs that sense gravity. These cells help the roots grow downwards towards the earth, a process known as gravitropism. This enables plants to anchor themselves securely in the soil and helps them access essential nutrients and water.
Plants are negatively geotropic, and grow away from gravity. Since the earth is the center of gravity as far as plants are concerned (not to mention us humans!), this of course means that plants grow away from the earth. This is because plants seek out sunlight, or whichever light they are being exposed to. The photons (light energy) make contact with the plants surface and results in the creation of a hormone known as auxin which causes cell elongation. Since this happens on the side exposed to the light, a plant regardless of it's position, will begin to angle towards the light. So if for instance you placed a light shining downwards and a plant upside down, the plant would grow 'backwards' so to speak and away from the earth and the source of gravity.
This is one method for drying off pots of bulbs as no water reaches the roots. With any other plants the growth will turn upwards towards the light. Eventually because of the lack of water the plant will die.
Your distance from plants does not affect gravity. Gravity is a force of attraction between objects with mass, such as the Earth and everything on it. Plants do not have a significant influence on the force of gravity acting on you based on how close you are to them.
Gravity affects the growth of plants whereby for a plant to grow vertically upright, it needs a strong structural base, and it also makes the roots to grow downwards and determines how tall a plant can get.
Geotroprism is the growth of plants in response to gravity.Main roots are positively geotropic while main stems are negatively geotropic.The significance of the tropic response is to enable the root to penetrate into the soil for better anchorage and obtain more water and minerals.
