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.
Living things have evolved mechanisms to adapt to changes in their environment through processes such as migration, hibernation, or changing behaviors. These responses help them survive and thrive in their changing surroundings.
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
Tropic responses are called tropism. It is the growth or turning movement of plants in response to an environmental stimulus. Nastic movements are non-directional responses to stimuli, independent of the stimulus's position.
Plants respond to touch stimuli through a process called thigmotropism, where they change their growth direction in response to touch. This is controlled by hormones like auxin and ethylene, which help regulate cell growth and movement in response to touch. Additionally, plants have specialized cells called mechanoreceptors that detect touch and trigger a cascade of signaling pathways to initiate a response.
Plants respond to stimuli through growth movements. For example, phototropism is their response to light, causing them to grow towards it. Thigmotropism is their response to touch, triggering growth in response to physical contact. These responses help plants adapt and survive in their environment.

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.
Indian scientist Sir Jagadish Chandra Bose conducted pioneering research that demonstrated that plants respond to external stimuli. He observed and recorded plant responses to various stimuli such as light, sound, and touch, laying the foundation for the field of plant physiology.

Mastic movements involve reversible changes in the position of plant parts in response to external stimuli, such as the opening and closing of petals in flowers. Tropisms, on the other hand, are directional growth responses of plants towards or away from external stimuli, such as phototropism towards light or gravitropism towards gravity. Mastic movements are more direct and immediate, while tropisms involve slower, growth-oriented responses.
Animals respond more quickly to a stimulus as animals have a central nervous system and a brain. Nerves conduct impulses very quickly. Plants dont have nerves and any responses are produced by hormones and are thus slow.
An example of external stimuli is a loud noise that causes someone to cover their ears or flinch in response.
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.
The movements of plants in response to external stimuli are called tropisms. These include phototropism (response to light), gravitropism (response to gravity), and thigmotropism (response to touch).
Stimuli itself is of two types - external stimuli and internal stimuli. External stimuli refers to touch, pressure, heat etc. Internal stimuli refers to the stimuli produced by body components - like hormones etc.
