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.
Fingertips wrinkle due to a process called vasoconstriction, where blood vessels constrict in response to water exposure. This helps with grip in wet conditions by creating channels for water to drain. The wrinkling occurs automatically and is a temporary and reversible response.
This response is called, photoperiodism.

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).

Random movement in response to a stimulus is called kinesis. Kinesis is a non-directional response where the organism changes its rate of movement in response to a stimulus, but not the direction.
A plant's response to gravity is called gravitropism or geotropism.
The neuroendocrine system's defensive response to shock is called the stress response or the fight-or-flight response. This response involves the release of hormones such as adrenaline and cortisol to prepare the body to deal with a threatening situation.
