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

Answer:

The correct answer will be option-D

Explanation:

The aerotaxis movement experiment performed by the Theodor W. Engelmann played an important role in understanding the photosynthesis.

The experiment was performed on the <em>Spirogyra </em>filamentous algae which were exposed to a different wavelength of light.

The other aerobic bacteria present in the test tubes started moving and accumulated near the two regions of the <em>Spirogyra</em> where they were exposed to the blue and red light of the VIBGYOR.

The region receiving red and blue light produced more oxygen through photosynthesis which indicated that these two wavelengths of the light are more active for photosynthesis than any other wavelengths.

Thus, option-D is the correct answer.

Question # 9
weeeeeb [17]
Photosynthesis is a process by which plants use sunlight, water, and carbon dioxide to produce carbohydrates, and other biological compounds, which reduces the amount of carbon dioxide in the air. This is the difference between plants and animals. The carbon dioxide is stored in the plants until they decompose or are burned. So, for example, each fall when the trees lose their leaves and the plants die the level of carbon in the atmosphere goes up. The rest of the tree, bark etc., does not continue to absorb carbon. Plants only take in carbon so long as they are growing and not after they have reached their natural height. Planting trees and other plants is one component of the solution to global warming, but the number of plants we have now cannot consume more carbon than they already do, and there is some evidence that warmer temperatures make photosynthesis more difficult.
