gravity light and touch are the three stimuli for plant tropisms.
It is a scientific theory
Theory-practice-theory take existing theory in education, apply to distance learning, develop new theory Practice-research-theory see what is happening in distance learning, submit to research, develop theory from results Theory-theory-research/practice build on an initial theory to develop a second theory, then apply and test it
A common theory is a theory which has not been proven or a theory without evidence.

The three plant tropisms include geotropism, thigmotropism,hydrotropism and photoperiodism.
Tropisms

they are actions that a plant takes in order to increase its chance of survival. An example of a behavioral adaptation in plants are tropisms. Tropisms are the growth of plants toward sunlight.
tropisms
Tropisms, such as phototropism (response to light) and gravitropism (response to gravity), allow plants to adapt and grow towards essential resources like sunlight and water. For farmers, understanding and manipulating tropisms can help optimize plant growth and yield. By controlling factors that influence tropisms, farmers can ensure that crops receive adequate sunlight, water, and nutrients, leading to healthier and more productive harvests.
Tropisms are plant's response to a particular stimulas. Tropisms demostrate that plants can response to light, water, gravity and chemicals. We, humans know what we want and with our knowledge we seek for it. Unlike humans, plants doesn't know what they want and how to look for it. So plants response to stimulus in order to get what they want and to survive. Plants turn towards light in order to make food. Tropisms helps plants to survive as plants cannot move and has no knowledge.
There are five main types of tropisms: phototropism (response to light), geotropism (response to gravity), hydrotropism (response to water), thigmotropism (response to touch), and chemotropism (response to chemicals).
Charles Darwin and his son did an experiment in 1880 using grass plants which led to the discovery of phototropism, this discovery led to many other scientists wanting to find out other tropisms
