Answer

### Step-by-Step Solution

1. **Understanding the Linnaeus System of Classification**: The Linnaeus system, developed by Carolus Linnaeus, is an artificial classification system primarily based on observable characteristics of plants, particularly their reproductive structures.

2. **Classification Basis**: This system emphasizes the sexual characteristics of plants, focusing on the presence and absence of male and female sex organs. It also considers the total number of stamens (male reproductive parts) and carpels (female reproductive parts).

3. **Number of Classes**: Linnaeus classified plants into a total of 24 classes. This classification is significant as it categorizes plants based on their reproductive features.

4. **Fennaro-gamia and Cryptogamia**: Out of the 24 classes:
- 23 classes belong to **Fennaro-gamia**, which refers to plants that have visible sex organs.
- 1 class belongs to **Cryptogamia**, which includes plants with hidden sex organs.

5. **Conclusion**: Therefore, the Linnaeus system of classification contains a total of 24 classes, with the majority being Fennaro-gamia and a minority being Cryptogamia.

### Final Answer
The Linnaeus system of classification contains **24 classes of plants**.
