Question

Chlorophyll 'a' and 'b' shows maximum absorption in:

• A. Blue region
• B. Red region
• C. Blue and red region
• D. Yellow and violet region

Answer 1

The correct option is C Blue and red region

Chlorophyll 'a' is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light. Chlorophyll 'b' is a form of chlorophyll. It helps in photosynthesis by absorbing light energy. It is more soluble than chlorophyll in polar solvents because of its carbonyl group. Its color is yellow and primarily absorbs blue light.

So, the correct answer is option C.
