A plant is observed to have deep roots and tendrils that wrap around objects. Which pair of tropisms correctly describe these responses?(1 point)
Responses
The pair of tropisms that correctly describe these responses are:
- Phototropism (for the deep roots): Phototropism is the growth or movement of an organism in response to light. In this case, the deep roots of the plant are an example of positive phototropism, meaning they grow towards the direction of light (since roots typically grow downwards, deeper roots are an indicator of positive phototropism).
- Thigmotropism (for the tendrils wrapping around objects): Thigmotropism is the growth or movement of an organism in response to touch or contact stimuli. In this case, the tendrils wrapping around objects demonstrate positive thigmotropism, as they grow towards and curl around objects that they come into contact with.
