Correct

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?

:

Red and blue

Question 2

3 out of 3 points

Correct

Does the rate of photosynthesis increase with increasing light intensity?

Yes, but it levels off at 1600-2400 ft-candles.

Question 3

3 out of 3 points

Correct

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 6

3 out of 3 points

Correct

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 7
