What was the purpose of the experiments conducted by T.W Engelmann?
To discover the location of chlorophyll in plant cells
To determine the main component of light that drives photosynthesis
To determine the role of aerobic bacteria in photosynthesis
To determine the role of water in photosynthesis
Solution
T.W Engelmann used a prism to split light into its spectral components and then illuminated a green alga to determine the main component of light that drives photosynthesis. He observed that the bacteria accumulated mainly in the region of blue and red light of the split spectrum, leading to the description of the first action spectrum of photosynthesis.
