Vedclass · Answer

(D) $Engelmann$'s experiment used a prism to split light into its spectral components and illuminated $Spirogyra$ placed in a suspension of aerobic bacteria. He observed that the bacteria accumulated mainly in the regions of blue and red light of the split spectrum. Since these bacteria require oxygen for respiration,their accumulation indicated that the rate of photosynthesis was highest in these regions. Therefore,it demonstrated that both blue and red wavelengths are effective for photosynthesis.
