$ Process of separation of photosynthetic pigments is called chromatography
! Chromatophore have accessory photosynthetic pigments such as phycocyanin.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that the process of separation of photosynthetic pigments is called chromatography. This is true as chromatography is a technique used to separate different pigments based on their solubility and interaction with the stationary phase.

2. **Identifying Photosynthetic Pigments**: In plants, there are several key pigments involved in photosynthesis. The main pigments include:
- Chlorophyll A (blue-green color)
- Chlorophyll B (yellow-green color)
- Xanthophyll (yellow color)
- Carotenoids (yellow to orange color)

3. **Role of Chromatography**: Chromatography allows us to separate these pigments from plant leaves. By applying a leaf extract to a chromatography medium, the pigments will move at different rates, allowing for their separation and identification.

4. **Understanding the Reason**: The reason states that chromatophores have accessory photosynthetic pigments such as phycocyanin. Chromatophores are specialized structures found in cyanobacteria that contain various pigments necessary for photosynthesis.

5. **Evaluating the Reason**: While chromatophores do contain photosynthetic pigments, phycocyanin is specifically found in cyanobacteria and is not present in the chromatophores of all organisms. Therefore, the statement about phycocyanin being an accessory pigment in chromatophores is incorrect.

6. **Conclusion**: The assertion is correct, while the reason is incorrect. Thus, the final answer is that the assertion is true and the reason is false.
