The correct option for the question regarding the form in which carbohydrates are stored in Rhizopus is C. Glycogen. Detailed Explanation:

1. Understanding Rhizopus:
2. Rhizopus is a genus of fungi, commonly known as bread molds. It is part of the Zygomycetes class and is often found in decaying organic matter, including bread and fruits.
3. Carbohydrate Storage in Fungi:
4. Fungi, including Rhizopus, store carbohydrates in specific forms that are suitable for their metabolic needs. The primary forms of carbohydrate storage in fungi are glycogen and starch.
5. Why Glycogen is the Correct Answer:
6. Glycogen is a polysaccharide that serves as a form of energy storage in animals and fungi. It is a branched polymer of glucose units. In Rhizopus, glycogen is the main storage carbohydrate, allowing the organism to store energy efficiently and mobilize it when needed.
7. Glycogen is particularly advantageous for fungi because it can be rapidly broken down into glucose when energy is required, especially during periods of growth or reproduction.
8. Why the Other Options are Incorrect:
9. A. Glucose: While glucose is a simple sugar and an important energy source, it is not stored in its free form in organisms. Instead, it is typically stored as glycogen or starch. Therefore, glucose itself is not a storage form.
10. B. Paramylon: This is a storage polysaccharide found in certain algae, particularly in the genus Euglena. It is not associated with Rhizopus or other fungi. Thus, this option is irrelevant in the context of Rhizopus.
11. D. Starch: Starch is a common storage carbohydrate in plants and some algae, but it is not the primary storage form in fungi. While some fungi can produce starch, Rhizopus specifically stores carbohydrates as glycogen.

Summary of Key Points:

• Rhizopus stores carbohydrates primarily in the form of glycogen, which is a branched polysaccharide of glucose.
• Glycogen allows for efficient energy storage and mobilization in fungi.
• Other options like glucose, paramylon, and starch do not accurately represent the carbohydrate storage method in Rhizopus.

Revision Summary:

• Rhizopus stores carbohydrates as glycogen.
• Glycogen is a branched polymer of glucose, suitable for rapid energy release.
• Glucose is not stored directly; paramylon is not found in Rhizopus; starch is primarily a plant storage form.
• Understanding the specific storage forms of carbohydrates in different organisms is crucial for biology studies.
