Further Explanation:
<u>Photosynthesis is a biological process that can be used by plants and other organisms such as blue green algae for the conversion of light energy into chemical energy for the formation of their food.</u> For photosynthesis sunlight, water, and carbon dioxide is required. Chlorophyll ‘a’ is the main light-absorbing pigment for photosynthesis.
Chlorophyll serves as main light absorbing photosynthetic pigment. It plays an essential role in the transformation of light energy into chemical energy. It is found in the thylakoid membrane of the chloroplast of the plant cell. Chlorophyll ‘a’ is serves as the essential and primary pigment for photosynthesis whereas chlorophyll ‘b’ is serves as accessory pigment as it is not essentially required for photosynthesis.
All the photosynthetic organisms have chlorophyll ‘a’ rather than chlorophyll ‘b’. Chlorophyll ‘a’ acts as primary electron acceptor in the electron transport chain. As light is absorbed from the violet-blue as well as orange-red region of electromagnetic spectrum energy is transferred to the reaction center. Chlorophyll ‘a’ also donates two electrons in their excited state to the electron transport chain. In an electron transport chain, it captures solar energy of sun and transforms it into chemical energy that can be used by the photosynthetic organisms for further cellular processes.
