The diagram shows the famous Engelmann experiment that helped us understand important aspects of the process of photosynthesis. What conclusion can be drawn by the pattern of accumulation of aerobic bacteria shown in the diagram?
| 1. | Excess carbon dioxide is released by the alga in the area of accumulation. |
| 2. | Only red and violet lights are effective for photosynthesis. |
| 3. | In the areas of accumulation, most oxygen was liberated by the alga. |
| 4. | Bacteria are attracted to red and blue light. |
The Engelmann experiment shown in the given diagram helped to understand the relationship between:
| 1. | bacteria and the alga used in the experiment. |
| 2. | the rate of respiration in aerobic bacteria and wavelengths of light. |
| 3. | wavelengths of light and the oxygen released during photosynthesis. |
| 4. | rates of oxygen liberation by alga and carbon dioxide liberated by the bacteria. |
Identify the incorrectly matched pair:
| 1. | PS I | P700 is reaction center |
