Current Question (ID: 11306)

Question:

One scientist cultured Cladophora in a suspension of Azotobacter and illuminated the culture by splitting light through a prism. He observed that bacteria accumulated mainly in the region of:

Options:

1. Violet and green light
2. Indigo and green light
3. Orange and yellow light
4. Blue and red light

Solution:

The scientist observed that bacteria accumulated mainly in the region of blue and red light. This is because chlorophyll, the primary pigment involved in photosynthesis, absorbs light most efficiently in the blue and red regions of the visible spectrum. Therefore, these wavelengths of light are most effective in driving photosynthesis and producing the ATP and NADPH required for growth and metabolism. Options 1, 2, and 3 are less likely to be correct as they do not include the red region of the visible spectrum, which is known to be important for photosynthesis. Additionally, violet and indigo light have shorter wavelengths and higher energy than blue light, while orange and yellow light have longer wavelengths and lower energy than red light.
