What did Engelmann conclude about the congregation of bacteria in the red and blue areas? Bacteria congregated in these areas because these areas had the most oxygen being released. Bacteria released excess carbon dioxide in these areas Bacteria congregated in these areas due to an increase in the temperature of the red and blue light. Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths. Bacteria congregated in these areas due to an increase in the temperature caused by an increase in photosynthesis

During an experiment, filamentous green algae were illuminated with light along a spectrum of different wavelengths. Aerobic bacteria were added, and he noticed that the bacteria congregated in certain regions along the spectrum where red and blue light was found. What can you conclude about the congregation of bacteria in the red and blue areas? Bacteria congregated in these areas due to the increased amount of oxygen released. Bacteria release excess carbon dioxide in these areas. Bacteria are attracted to red and blue light. Bacteria congregated in these areas due to an increase in the temperature of red and blue light.

Thomas Engelmann illuminated a filament of algae with light that passed through a prism, thus exposing different segments of algae to different wavelengths of light. He added aerobic bacteria and then noted in which areas the bacteria congregated. He noted that the largest groups were found in the areas illuminated by the red and blue light. 11. What did he conclude about the congregation of bacteria in the red and blue areas? a. Bacteria released excess CO2 in these areas. b. Bacteria congregated in these areas due to an increase in the temperature of the red and blue light. c. Bacteria congregated in these areas because these areas had the most O2 being released. d. Bacteria are attracted to red and blue light and thus these wavelengths are more reactive than other wavelengths. 12. The purpose of this experiment was to determine a. the relationship between heterotrophic and autotrophic organisms. b. the relationship between wavelengths of light and the rate of aerobic respiration. c. the relationship between wavelengths of light and the amount of heat released. d. the relationship between wavelengths of light and the rate of photosynthesis. 13. In plant cells, ATP is made in response to light. An electron transport chain is involved. This electron transport chain is found in the a. thylakoid membranes of chloroplasts. b. stroma of chloroplasts. c. inner membrane of mitochondria. d. matrix of mitochondria. 14. All of the following statements are correct regarding the light-independent (dark) reactions of photosynthesis except a. The energy source utilized is the ATP and NADPH obtained through the light reaction. b. This reaction begins soon after sundown and ends before sunrise. c. The 5-carbon sugar RuBP is constantly being regenerated. d. The pathway used is the Calvin cycle. 15. The color of light least effective in driving photosynthesis is a. blue. b. red. c. orange. d. green.
