Question

Quizplus · Accepted Answer

Blue light induces curvature in coleoptile most effectively. This has been demonstrated in numerous experiments and is believed to be due to the activation of phototropin proteins, which are sensitive to blue light. Red light, on the other hand, is known to inhibit coleoptile growth and often induces a straightening response. Therefore, B) blue is the best choice for the colour of visible light that induces curvature in coleoptile most effectively.
