The starch stored in red algae is:

Options

A. laminarin starch
B. glucose
C. Aoridean starch
D. cellulose

Answer

**Step-by-Step Solution:**

1. **Identify the Group of Algae**: The question specifically asks about red algae. Red algae belong to the group known as Rhodophyta.

2. **Understand the Reserve Food Material**: In various types of algae, different substances are stored as reserve food materials. For red algae, it is important to identify what they store.

3. **Review Options**: The options given are:
- A. Laminarin starch
- B. Glucose
- C. Floridian starch
- D. Cellulose

4. **Determine the Correct Answer**: Red algae primarily store Floridian starch as their reserve food material. This starch is structurally similar to amylopectin (found in starch) and glycogen.

5. **Conclusion**: Therefore, the correct answer to the question is **C. Floridian starch**.
