Which form of phytochrome would you expect to accumulate in a plant that is receiving full sunlight? Explain your answer
What will be an ideal response?
In full sun a plant is receiving more red wavelengths of light than far-red. Therefore, phytochrome red is converted to phytochrome far-red. Phytochrome far-red would be expected to accumulate in a plant receiving full light.
