प्रश्न
Suppose there were plants that had a high concentration of Chlorophyll b, but lacked chlorophyll a, would it carry out photosynthesis? Then why do plants have chlorophyll b and other accessory pigments?
उत्तर
- Since chlorophyll is the principal pigment and the reaction centre, plants lacking it are unable to perform photosynthesis.
- It carries out the basic processes of photosynthesis, which is the transformation of light into chemical or electrical energy. Accessory pigments are other types of photosynthetic pigments.
- They increase the range of light that photosynthetic pigments absorb by absorbing light energy at various wavelengths. Chlorophylla receives the absorbed energy from these pigments.
