The stored food in blue-green algae is

Options

A. Starch
B. Glucose
C. Cellulose
D. Related to glycogen.

Answer

**Step-by-Step Solution:**

1. **Understanding Blue-Green Algae**: Blue-green algae, also known as cyanobacteria, are photosynthetic prokaryotes that can produce their own food through the process of photosynthesis.

2. **Identifying Stored Food**: The primary stored food in blue-green algae is a type of carbohydrate. In many cyanobacteria, this stored food is in the form of **glycogen**, which is a polysaccharide that serves as an energy reserve.

3. **Additional Stored Substances**: Besides glycogen, some blue-green algae may also store other substances like **cyanophycin**, which is a nitrogen storage compound, but glycogen is the most common and significant form of stored food.

4. **Conclusion**: Therefore, the stored food in blue-green algae is primarily **glycogen**.
