In which part of the light spectrum is photosynthesis hindered?
Think it through first, then pick an option.
- a Blue
- b Green
- c Orange
- d Red
Answer and explanation
Correct answer: b Green
Photosynthesis does not go well in green (and yellow) light, so it is hindered there.
Why the other options are wrong
- a Blue: Photosynthesis goes well in blue light, so it is not hindered there.
- c Orange: Orange is one of the parts of the spectrum that suit photosynthesis well.
- d Red: Photosynthesis goes well in red light too.
