Definitions
- Describing the growth or movement of a plant in response to an external stimulus, such as light or gravity. - Referring to the innate tendency of an organism to move or grow towards or away from a particular stimulus. - Talking about the directional response of an organism to an external stimulus.
- Referring to the ability of an organism to detect and respond to changes in its environment. - Describing the degree of responsiveness or reactivity of an organism to a particular stimulus. - Talking about the susceptibility of an organism to external factors or influences.
List of Similarities
- 1Both involve the response of an organism to an external stimulus.
- 2Both are related to the perception and detection of environmental changes.
- 3Both can be influenced by genetic and environmental factors.
- 4Both are important for the survival and adaptation of organisms.
- 5Both can be observed in various organisms, including plants and animals.
What is the difference?
- 1Directionality: Tropism involves a directional response towards or away from a stimulus, while sensitivity does not necessarily have a specific direction.
- 2Type of response: Tropism involves a physical response, such as growth or movement, while sensitivity can involve various types of responses, including behavioral and physiological responses.
- 3Scope: Tropism is typically used to describe the response of plants, while sensitivity can be applied to a wider range of organisms.
- 4Timing: Tropism is often a slower response that occurs over a longer period, while sensitivity can be a more immediate response.
- 5Measurement: Tropism can be measured by observing the direction and extent of growth or movement, while sensitivity can be measured by various methods, including behavioral tests and physiological measurements.
Remember this!
Tropism and sensitivity both refer to the response of an organism to an external stimulus. However, tropism specifically involves a directional physical response, such as growth or movement, while sensitivity can involve various types of responses and does not necessarily have a specific direction. Tropism is typically used to describe the response of plants, while sensitivity can be applied to a wider range of organisms.
