Phototropism: the growth of plants in response to light, such as bending towards a light source. Geotropism (gravitropism): the growth of plants in response to gravity, such as roots growing downward and stems growing upward. Thigmotropism: the growth response of plants to touch or mechanical stimuli, such as vines coiling around a support. Hydrotropism: the growth response of plants in search of water, where roots grow towards a water source.
a "tropism"; geotropism for response to gravity and phototropism for response to light
geotropism
Roots exhibit positive gravitropism, growing downwards in response to gravity. They also show positive hydrotropism, growing towards moisture to optimize water uptake. Additionally, roots demonstrate negative phototropism, avoiding light to remain underground where they are protected.
Hydrotropism is a plant's growth reaction in which the path of growth is formed by a gradient or stimulus in water concentration. Phototropism commonly occurs in plants but can also take place in other beings like fungi.
I believe that the answer to your question would be a tropism. A tropism is a force that applies to an object, making it move somehow. For example, a plant that grows towards the ground would have a "positive gravitropism" because it is growing towards the ground. Also, a plant that grows towards the sun would have a "positive phototropism" because it grows towards light. There are many other types of tropisms that apply to chemicals, seasonal changes, and so forth, but the ones that I talked about are the two most common and basic types of tropisms. I hope I answered your question.
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.
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
Snakes and lizards. Also fishes.
...Negative tropism is a change in text of a song due to mishearing the lyrics or inaccurate memory of the lyrics. It results in multiple versions of songs after a while. It is very common in English and Scottish balladry, as well as in Appalachian ballads.
Certain plants react to gravity by growing against it or towards it. It is the tropism of gravity called a geotropism. For example, if a potted plant falls over then it will continue to grow towards the sky. If a mudslide occurs and it drastically tilts the land where a tree grows, the tropism allows the tree to grow upwards. Alternatively, geotropism works for roots as well. Roots will respond to gravity by growing downwards. It can be observed that no matter which way a seed is planted the roots and the shoots respond to gravity in opposite ways. Plant hormones, auxins are responsible for this response. Phototropism is the response of plants to light.
Geotropism (also called gravitropism) is the turning or growth movement by a plant or fungus in response to gravity. Roots show positive geotropism (grow toward gravity - down) and stems show negative geotropism (grow away from gravity - up).
