Plant growth hormones e.g. IAA.
Mimosa (makahiya) have thorns to warn the animals and people not to go near them. Plants responses are called 'tropism'. The bending of the plant towards the light is called 'phototropism'. Plants response to gravity is called 'gravitropism' or 'geotropism'. The plants response to touch is called 'thigmotropism'. the response to a source of water is called 'hydrotropism'. Plants respond to 'environmental stimuli'. Plants responses to stimuli enable them to survive. These are the protective structure of a Mimosa and other behavioral adaptation of Plants.
Plants are made from chemicals and they release chemicals.
Some chemicals make plants grow. They are called fertilizers. Some chemicals plants make plants die. When intentionally applied, they are the type of pesticide called herbicides. Some chemicals do not affect plants.
Light. Tropisms are growth responses to stimuli. Photo-tropism = light-growth
Plants don't excel in locomotion, that is, the ability to move on their own. They show a sensitivity to external stimuli, such as food, by consuming it.
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.

Change in the environment is external stimuli and the response of life to external stimuli is adaptation or extinction.

The stimuli that plants respond to include light, water and gravity. Plants grow towards light (phototropism). Also in some plants the flowers will follow the sun as it moves across the sky. Plant roots grow towards water (hydrotropism). Plant roots grow towards gravity/towards the centre of the earth (geotropism). Source(s): I'm a biology teacher. this is bullcrap it is fake
Plants do not have a state of consciousness, so they do not have "feelings" in the traditional sense of the word. They do respond to stimuli and produce different hormones in response to these conditions.
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.
Plants DO NOT respond to stimuli
Plants are made from chemicals and they release chemicals.
Some chemicals make plants grow. They are called fertilizers. Some chemicals plants make plants die. When intentionally applied, they are the type of pesticide called herbicides. Some chemicals do not affect plants.
