Students have asked these similar questions
a. What are the two basic components of phytochrome?
b. Explain how phytochrome responds to different wavelengths of light. How does this account for the phenomenon of photoreversibilty?
Discuss other morphological differences between sunny and shady set-ups of mung bean in relation to phototropic response of plants.
Characteristics
sunny
shaded
Leaf color
Lime Green
Pale Green
Direction of Growth
Grows upward towards the direction of sunlight
Oriented in the direction of the light but growth is bent downward
Using the provided figure, describe the importance of the two phytochrome systems in controlling de-etiolation and green stem elongation under full sun and shade. Include the key mechanisms and temporal changes in control of this process.
