The stored food is very much similar to amylopectin and glycogen in structure in algal group which can be also characterized by

Options

A. Their greater concentrations in warm marine areas
B. Their absence in well-lighted regions close to the surface of water
C. Their distribution at greater depths in oceans where relatively more light penetrates
D. Absence of multicellular organisms

Answer

**Step-by-Step Solution:**

1. **Identify the Stored Food**: The stored food in the algal group that is similar to amylopectin and glycogen is known as **Floridian starch**.

*Hint: Look for the name of the starch that resembles amylopectin and glycogen in structure.*

2. **Understand the Composition**: Floridian starch is composed of both **amylose and amylopectin**, which are polysaccharides.

*Hint: Recall the components that make up starch and their structural similarities.*

3. **Classify the Algae**: Floridian starch is primarily found in the class of algae called **Rhodophyce**, commonly known as **red algae**.

*Hint: Think about the classification of algae and the specific group that contains Floridian starch.*

4. **Identify the Pigment**: The red color of Rhodophyce is due to the presence of a pigment called **R-phycoerythrin**.

*Hint: Consider what gives red algae their characteristic color.*

5. **Determine the Habitat**: Rhodophyce predominantly thrive in **warm marine areas**, indicating their preferred habitat.

*Hint: Reflect on the environmental conditions that are favorable for red algae growth.*

6. **Evaluate the Options**: Among the options provided, the correct characterization of the stored food is that it has a **greater concentration in warm marine areas**.

*Hint: Compare the options to find the one that accurately describes the habitat of Rhodophyce.*

**Final Answer**: The stored food in the algal group, which is similar to amylopectin and glycogen, is characterized by a greater concentration in warm marine areas.
