Leaves originate from _____meristem.

Answer

**Step-by-Step Solution:**

1. **Understanding Meristems**: Meristems are regions in plants where cells are actively dividing. They are responsible for the growth of the plant.

2. **Types of Meristems**: There are two main types of meristems:
- **Apical Meristem**: Found at the tips of roots and shoots, responsible for primary growth (lengthening).
- **Lateral Meristem**: Responsible for secondary growth (thickening).

3. **Identifying the Origin of Leaves**: Leaves are formed from the shoot part of the plant. The specific type of meristem that gives rise to leaves is the shoot apical meristem.

4. **Function of Leaves**: Leaves are crucial for photosynthesis, the process by which plants convert light energy into chemical energy. They contain structures called stomata that facilitate gas exchange.

5. **Conclusion**: Therefore, leaves originate from the shoot apical meristem.

**Final Answer**: Leaves originate from the shoot apical meristem.
