Answer 2

The reason why is chlorophyll-a called essential pigment is as follows:

• For photosynthesis of plants, chlorophyll-a is the primary pigment.

• Chlorophyll-a is considered as the most essential photosynthetic pigment because in case of the conversion of light energy to chemical energy, it is directly involved.
• From wavelengths of orange-red and green-yellow lights, most energy is absorbed by it.
• All other pigments are considered as accessory pigment.
