Assertion: Leaf colouration is due to the presence of four pigments - ...
Chlorophyll a is found in all photosynthetic plants except bacteria. Hence, it is called as universal photosynthetic pigment. It is also called primary photosynthetic pigment because it performs primary reaction of photosynthesis which involves conversion of light into chemical energy. Other photosynthetic pigments like chlorophyll b, carotenes and xanthophylls are called accessory pigments.

Assertion Analysis
The assertion states that leaf coloration is due to the presence of four pigments: Chlorophyll a, chlorophyll b, xanthophylls, and carotenoids. This statement is true. These pigments contribute to the color of leaves and play essential roles in photosynthesis.
Reason Analysis
The reason states that chlorophyll b is the chief pigment associated with photosynthesis. This statement is false. While chlorophyll b assists in capturing light energy, chlorophyll a is the primary pigment responsible for the actual conversion of light energy into chemical energy during photosynthesis.
Conclusion
Given the analysis:
- The assertion is true because leaf coloration involves multiple pigments.
- The reason is false as chlorophyll a is the chief pigment in photosynthesis, not chlorophyll b.
Thus, the correct option is:
c) If Assertion is true but Reason is false.
Key Points Summary
- Leaf Coloration:
- Involves multiple pigments: Chlorophyll a, chlorophyll b, xanthophylls, carotenoids.
- Contributes to the variety of colors seen in leaves.
- Photosynthesis:
- Chlorophyll a is the primary pigment for capturing light energy.
- Chlorophyll b supports but is not the main pigment.
This distinction clarifies why the assertion is true while the reason is false, leading to the correct answer being option 'C'.
