In Cacti, the succulence is mostly in

Options

A. Stems
B. Leaves
C. Roots
D. All the above

Answer

To answer the question "In Cacti, the succulence is mostly in," we will analyze the structure of cacti and identify where the succulence is primarily located.

### Step-by-Step Solution:

1. **Understanding Succulence**:
- Succulence refers to the ability of a plant to store water in its tissues. This adaptation is crucial for survival in arid environments where water is scarce.

2. **Identifying Plant Structures**:
- In cacti, the main structures to consider are the stems, leaves, and roots. Each of these parts can play a role in water storage.

3. **Analyzing Cactus Stems**:
- Cacti have thick, fleshy stems that are designed to store large amounts of water. This is the primary area of succulence in cacti.

4. **Examining Cactus Leaves**:
- The leaves of cacti are typically reduced to spines (thorns) to minimize water loss through transpiration. Since they are not fleshy and do not store water, they are not the main site of succulence.

5. **Looking at Cactus Roots**:
- Cacti have shallow, wide-spreading roots that help them absorb water quickly from light rains. However, these roots are not designed for water storage and are not succulent.

6. **Conclusion**:
- Based on the analysis, the succulence in cacti is mostly found in the stems. Therefore, the correct answer is "stems."

### Final Answer:
In Cacti, the succulence is mostly in **stems**.
