1 answer

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.
