Cyanophycean granules and glycogen granules are examples of

Options

A. Microbodies
B. Inclusion bodies
C. SER
D. Lysosomes

Answer

To solve the question regarding cyanophycean granules and glycogen granules, we need to identify what type of cellular structures these granules represent. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Terms
- **Cyanophycean Granules**: These are granules found in cyanobacteria (blue-green algae) that store food in the form of cyanophycean starch.
- **Glycogen Granules**: These are granules that store glycogen, a polysaccharide made up of glucose units, in various organisms including animals and fungi.

**Hint**: Identify the organisms and the type of substances these granules store.

### Step 2: Identify the Nature of Granules
Both cyanophycean granules and glycogen granules are not membrane-bound organelles. They are simply storage forms of nutrients within the cell.

**Hint**: Consider whether the structures are membrane-bound or not.

### Step 3: Classify the Granules
Since both types of granules serve as storage for nutrients and are not surrounded by membranes, they are classified as **inclusion bodies**. Inclusion bodies are aggregates of substances within the cytoplasm that serve as storage.

**Hint**: Think about the classification of cellular structures based on their membrane presence and function.

### Step 4: Eliminate Other Options
- **Microbodies**: These are membrane-bound organelles containing enzymes (e.g., peroxisomes) and do not fit the description of granules.
- **Smooth Endoplasmic Reticulum (SER)**: This is involved in lipid synthesis and is also a membrane-bound structure, not related to granules.
- **Lysosomes**: These contain hydrolytic enzymes and are also membrane-bound, thus not applicable here.

**Hint**: Compare the characteristics of the provided options with the nature of the granules.

### Conclusion
Based on the analysis, both cyanophycean granules and glycogen granules are classified as **inclusion bodies**.

**Final Answer**: Inclusion bodies
