)Movement or activity of an organism in response to a stimulus such as light.
Movement in response to light is called phototaxis, and in response to chemicals is chemotaxis. More specifically, movement towards a stimulus is positive and away from is negative. For example, positive chemotaxis is movement of a cell towards nutrients.
Phototropism is the movement of an organism in response to light. Plants, for example, can exhibit positive phototropism by growing towards a light source to optimize photosynthesis. Negative phototropism is when an organism moves away from light, such as the roots growing down into the soil away from light.
tropism
Response means reaction, as in a movement, change, or emission (like heat, light, or sound).
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.
Gentle air movement is typically referred to as a breeze. It is characterized by a light, refreshing flow of air that is mild and soothing.
when the fixed part of a stationary plant moves in response to a stimulus the reaction is known as tropic movement.or the movement in which fixed part of stationary plant moves in response to a stimulus is known as tropic movement or tropism.
Tropism is the movement of a plant away from or toward a stimulus. The most easily found example of tropism is a plant's response to light. Plants tend to grow toward the light. This tendency is called 'phototropism'.
