The correct Answer is:
To solve the question regarding the classification of Volvox and Polysiphonia, we can follow these steps: ### Step 1: Identify the Classes of Algae - **Volvox** is a member of the class **Chlorophyceae**, which includes green algae. - **Polysiphonia** is a member of the class **Rhodophyceae**, which includes red algae. ### Step 2: Analyze the Statements Now, we need to evaluate the statements provided in the question based on the classification of these algae. 1. **Statement 1**: "Cellulose and algin are the components of the cell wall of member A." - **Analysis**: Member A is Volvox (green algae). Green algae have cellulose in their cell walls, but **algin** is not found in green algae; it is typically found in brown algae. Therefore, this statement is **incorrect**. 2. **Statement 2**: "Floridane starch is stored food material in B." - **Analysis**: Member B is Polysiphonia (red algae). Red algae store their food as **Floridane starch**. This statement is **correct**. 3. **Statement 3**: "Chlorophyll-A, C and Fucoxanthin are photosynthetic pigments found in Class A." - **Analysis**: Class A is Chlorophyceae (green algae). Green algae primarily contain **Chlorophyll A and B**. **Fucoxanthin** is a pigment found in brown algae (Phaeophyceae). Therefore, this statement is **incorrect**. 4. **Statement 4**: "Two unequal flagella are found in member of B." - **Analysis**: Member B is Polysiphonia (red algae). Red algae do not have flagella; they are non-motile. This statement is **incorrect**. ### Step 3: Conclusion The only correct statement among the options provided is the second one: "Floridane starch is stored food material in B." ### Final Answer The correct statement is: **Floridane starch is stored food material in B (Polysiphonia).** ---
