Detailed explanation-1: -Green plants shows blue and orange-red light. The complementary color for blue and orange-red light is green and yellow. The halobacteria absorbs the yellow and green wavelength of light and reflects the purple color. Thus, the correct answer is option (C).

Detailed explanation-2: -Halobacterium has a photosynthetic membrane that is colored purple Its photosynthetic action spectrum is exactly complementary (opposite to) the action spectrum for green plants. What wavelengths of light do the Halobacterium photosynthetic pigments absorb? blue and red Want to learn this set quickly?

Detailed explanation-3: -Halobacterium halobium is attracted by green and red light and repelled by blue-green and shorter wavelength light.

Detailed explanation-4: -Action Spectrum: Describes the wavelengths that actually drive photosynthesis.

Detailed explanation-5: -Chlorophylls found in bacteria are called bacteriochlorophylls. Photosynthetic systems also contain another pigment, pheophytin (bacteriopheophytin in bacteria), which plays a crucial role in the transfer of electrons in photosynthetic systems.
