Consider the following statements regarding the major pigments and stored food in the different groups of algae and select the correct options given
(A) In chlorophyceae the stored food material is starch and the major pigments are chlorophyll-a and d
(B) In phaeopphyceae, laminarin is the stored food and major pigments are chlorophyll-a and b
(C) In rhodophyceae, floridean starch is the stored food and the major pigments are chlorophyll-a, d and phycoeythrin.

Options

A. (a) is correct, but (b) and (c) are wrong.
B. (a) and (b) are correct, but (c) is wrong.
C. (a) and (c) are correct, but (b) is wrong.
D. (b) is correct, but (a) and (c) are wrong

Answer

To solve the question regarding the major pigments and stored food in different groups of algae, we will analyze each statement one by one.

### Step 1: Analyze Statement A
- **Statement A**: In Chlorophyceae, the stored food material is starch, and the major pigments are chlorophyll-a and d.
- **Analysis**: Chlorophyceae, also known as green algae, indeed stores food in the form of starch. However, the major pigments present are chlorophyll-a and chlorophyll-b, not chlorophyll-d.
- **Conclusion**: Statement A is **incorrect**.

### Step 2: Analyze Statement B
- **Statement B**: In Phaeophyceae, laminarin is the stored food, and major pigments are chlorophyll-a and b.
- **Analysis**: Phaeophyceae, or brown algae, do store food as laminarin, but they also store mannitol. The major pigments present in Phaeophyceae are chlorophyll-a and chlorophyll-c, along with fucoxanthin, not chlorophyll-b.
- **Conclusion**: Statement B is **incorrect**.

### Step 3: Analyze Statement C
- **Statement C**: In Rhodophyceae, floridean starch is the stored food, and the major pigments are chlorophyll-a, d, and phycoerythrin.
- **Analysis**: Rhodophyceae, or red algae, do store food as floridean starch. The major pigments present are chlorophyll-a, chlorophyll-d, and phycoerythrin, which gives them their red color.
- **Conclusion**: Statement C is **correct**.

### Final Conclusion
- **Correct Statements**: Only Statement C is correct, while Statements A and B are incorrect.

### Summary of the Correct Options:
- The correct option is that **only Statement C is correct**.
