Question

Which experimental question were the students most likely trying to answer? How does thigmotropism affect plant growth? How does gravitropism affect plant growth? What does hydrotropism look like in bean plants? What does phototropism look like in bean plants?

Answer 1

Thigmotropism is a directional growth movement of curvature which occurs in response to stimulus of contact. Thigmotropism is found in twiners and tendrils. After initial contact with support due to nutation, the tendril or twiner shows less growth in the region of contact and more growth on the other side. As a result they bend over the support.
