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.
OK there's 4 tropisms hydro tropism (when plant grows towards water) thigmatropism, (when plant grows towards touch) gravitropism (grows right side up is turned upside down) and photo tropism (grows towards light)
This change in direction is called gravitropism. Plants respond to gravity by growing roots downward (positive gravitropism) and shoots upward (negative gravitropism). This mechanism helps plants optimize their growth by maintaining stable positions in relation to gravity.
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.
Thigmotropism is a plant's response to touch or physical contact with objects in its environment. It involves the plant's ability to grow or change direction in response to mechanical stimulation, allowing it to adapt and interact with its surroundings effectively.
It is a response called phototropism, where the plant grows towards light as a result of the stimulus of light perception.
A plant's response to gravity is called gravitropism or geotropism.
Autotropic & geotropic
Phototropism is the change in the way a plant grows in response to sunlight. This process involves the plant bending towards the light source to optimize its exposure to sunlight for photosynthesis.
The way a plant grows or bends due to gravity is called geotropism.

A directional plant response, also known as tropism, is the growth or movement of a plant in response to a directional stimulus, such as light, gravity, or touch. For example, phototropism is when a plant grows towards a light source. These responses allow plants to adjust their growth and development to optimize their chances of survival and reproduction.
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

Phototropism refers to a plant's response to light, where the plant grows toward or away from a light source.
The root grows downward due to gravitropism, a plant's response to gravity, while the shoot grows upward towards light through phototropism, a plant's response to light. These directional growth patterns enable the root to anchor the plant and absorb water and nutrients from the soil, while the shoot reaches for sunlight to undergo photosynthesis for energy production.
