Options

A. Rounded grains
B. Ellipsoid grains
C. Elongated granules
D. Flat ellipsoid granules.

Answer

### Step-by-Step Solution:

1. **Understanding Glycogen**:
- Glycogen is a multi-branched polysaccharide that serves as a form of energy storage in animals, fungi, and bacteria. It is primarily composed of glucose units.

2. **Location of Glycogen**:
- Glycogen is mainly stored in the liver and muscles of the body. This storage form is crucial for maintaining glucose levels in the blood and providing energy during physical activity.

3. **Structure of Glycogen**:
- The structure of glycogen consists of granules. These granules are where glycogen is stored within cells.

4. **Identifying the Form of Glycogen**:
- The question asks for the specific form in which glycogen occurs. The options provided are:
1. Rounded grains
2. Ellipsoid grains
3. Elongated granules
4. Flat ellipsoid granules

5. **Correct Answer**:
- After analyzing the options, glycogen granules are best described as flat ellipsoid granules. Therefore, the correct answer is option 4: **flat ellipsoid granules**.
