Varied number of cisternae are present in Golgi apparatus

Answer

### Step-by-Step Solution:

1. **Understanding the Golgi Apparatus**: The Golgi apparatus is a crucial organelle in cells responsible for modifying, sorting, and packaging proteins and lipids that are synthesized in the endoplasmic reticulum (ER).

2. **Structure of the Golgi Apparatus**: The Golgi apparatus consists of a series of flattened membrane-bound sacs known as cisternae. These cisternae are essential for the organelle's function.

3. **Function of Cisternae**: The cisternae play a vital role in the packaging of proteins and lipids. They facilitate the processing and transport of these biomolecules to their respective destinations.

4. **Variation in Number of Cisternae**: The number of cisternae in the Golgi apparatus can vary. This variation is dependent on the activity level of the cell.

5. **Cell Activity and Cisternae Count**: In more active cells, where there is a higher demand for protein and lipid synthesis, the Golgi apparatus will have more cisternae to accommodate the increased workload. Conversely, in less active cells, the number of cisternae will be fewer.

6. **Conclusion**: Therefore, the statement that "varied number of cisternae are present in Golgi apparatus" is true. The number of cisternae is directly proportional to the activity of the cell.
