The correct pair of tropisms that describe the responses of a plant with deep roots and tendrils that wrap around objects is hydrotropism and thigmotropism.
- Hydrotropism refers to the growth of plant roots towards moisture (water).
- Thigmotropism is the growth response of plants to touch or physical contact, which is exhibited by tendrils wrapping around objects.
Therefore, the first option, hydrotropism and thigmotropism, accurately describes the observed characteristics of the plant.
