• Question
1
3 out of 3 points

At the start of the algal
filament experiments, the bacteria were evenly distributed throughout the
chamber. Subsequently, after the chamber
was flooded with white light, the bacteria were

• Question
2
3 out of 3 points

Given that the atmospheric
concentration of CO 2 is approximately 300 ppm,
is photosynthesis in the field limited by the concentration
of CO 2?

• Question
3
3 out of 3 points

Is photosynthetic 0 2 production
light-dependent?

• Question
4
3 out of 3 points

In the algal filament experiment,
after the algal filament was illuminated with light from the prism, the
bacteria were clumped along certain areas of the algal filament.Which
wavelengths of white light seem most photosynthetically effective?
