Algae with floridean starch as reserve food material are also characterized by

Options

A. Presence of chlorophyll b
B. Stacked thylakoids
C. Nonsulphated phycocolloids
D. Non-flagellate nature

Answer

To solve the question regarding algae with floridean starch as a reserve food material, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Type of Algae**:
- Algae that store floridean starch as a reserve food material are primarily red algae (Rhodophyta).

2. **Characteristics of Red Algae**:
- Red algae are characterized by the presence of specific pigments. They contain chlorophyll A, chlorophyll D, and accessory pigments such as phycoerythrin, which gives them their characteristic red color.

3. **Evaluate the Options**:
- **Option 1**: Presence of chlorophyll B - This is incorrect as red algae do not contain chlorophyll B.
- **Option 2**: Presence of thylakoids - Red algae do not have stacked thylakoids, so this option is also incorrect.
- **Option 3**: Non-sulfated phycobilins - These are absent in red algae, making this option incorrect as well.
- **Option 4**: Non-flagellate nature - This is correct as red algae are generally non-flagellate.

4. **Conclusion**:
- The correct characteristic of algae with floridean starch as reserve food material is that they are non-flagellate in nature.

### Final Answer:
The algae with floridean starch as reserve food material are characterized by being non-flagellate in nature.
