A plant is observed to have deep roots and tendrils that wrap around objects. Which pair of tropisms correctly describe these responses?

Question

hydrotropism and thigmotropism
phototropism and thigmotropism
hydrotropism and geotropism

Answer 1

The correct pair of tropisms that describe these responses is phototropism and thigmotropism. Phototropism refers to the response of plants to light, where they grow towards a light source. Thigmotropism, on the other hand, refers to the response of plants to touch or physical contact, where they wrap their tendrils around objects for support and stability.
