Options

A. 10
B. 50
C. 3
D. 65

Answer

To determine how many times the tropical areas have vascular plants compared to temperate areas, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Vascular Plants**:
- Vascular plants are plants that have specialized tissues (xylem and phloem) for transporting water and nutrients. They include a wide variety of species, such as trees, shrubs, and flowering plants.

2. **Comparing Tropical and Temperate Regions**:
- Tropical regions are characterized by warm temperatures, high humidity, and consistent sunlight throughout the year. This environment supports a rich diversity of vascular plants.
- Temperate regions, on the other hand, experience more significant temperature fluctuations and seasonal changes, which can limit the diversity of vascular plants.

3. **Species Richness**:
- The concept of species richness refers to the number of different species present in a given area. Tropical regions typically have a higher species richness compared to temperate regions due to their stable and favorable climatic conditions.

4. **Quantifying the Difference**:
- Based on studies and ecological data, it has been established that tropical areas can have up to 10 times more vascular plant species than temperate areas. This is attributed to the favorable conditions in tropical regions that allow for greater biodiversity.

5. **Conclusion**:
- Therefore, the answer to the question is that tropical areas have vascular plants approximately **10 times** more than temperate areas.

### Final Answer:
Tropical areas have vascular plants **10 times** more than temperate areas.
