Students have asked these similar questions
Why would nature evolve a key enzyme, rubisco, that is so sensitive to oxygen, resulting in photorespiration?
Consider plants that live in a forest's top, middle, or ground layer, as well as algae that live near the ocean's surface or in deep water. Would you expect the same photosynthetic pigments to be present in these different environments in the same species? Why do you think that is the case? What method would you use to test your hypothesis?
Engelmann's experiment was designed to determine ___.
What wavelengths comprise visible light
what colors attract bacteria
if bacteria are attracted to oxygen
if photosynthesis releases oxygen
if photosynthesis is impacted by the color of light
