Answer:

The distribution of chloroplasts in each algae cell was approximately the same.

The number of bacteria grouped at each wavelength (color) was approximately proportional to the amount of oxygen produced by this part of the algae.

Explanation:

Photosynthetic pigments absorb blue, red and green lights. The wavelength of light that is the most effective in driving photosynthesis is 420 nanometers, which corresponds to blue light.

The wavelength of 475nm and 650nm are most effective in driving photosynthesis.
