Stored food of Red algae is :-

Options

A. Floridean starch
B. Glycogen
C. Cyanophycean starch
D. Leucosin

Answer

**Step-by-Step Solution:**

1. **Identify the Group of Algae**: Recognize that the question pertains to red algae, which belong to the group known as Rhodophyta.

2. **Understand the Characteristics of Red Algae**: Red algae are primarily marine, multicellular organisms that are characterized by their eukaryotic cells. They lack flagella and centrioles.

3. **Determine the Type of Stored Food**: In red algae, the stored food reserve is specifically identified. The options provided include Floridian starch, glycogen, cyanophysin, starch, and glucosin.

4. **Eliminate Incorrect Options**:
- Glycogen is the stored food reserve in animals, so it is not applicable to red algae.
- Cyanophysin is associated with cyanobacteria (blue-green algae), thus not relevant here.
- Leucosin is found in yellow-green algae (chrysophytes), which also does not apply.
- Starch is a general term and does not specifically refer to the storage form in red algae.

5. **Conclude with the Correct Answer**: The correct stored food of red algae is Floridian starch. This is a unique form of starch that serves as an energy reserve for red algae and is also considered edible, providing energy, vitamins, and proteins.

**Final Answer**: The stored food of red algae is Floridian starch.
