Sclernchymatous patches as bundle sheath extensions are found in leaves of

Options

A. dicots
B. monocots
C. both of these
D. none of these

Answer

To answer the question "Sclerenchymatous patches as bundle sheath extensions are found in leaves of?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Leaves**:
- Leaves consist of various types of tissues, including the vascular tissues (xylem and phloem) and the bundle sheath, which surrounds the vascular bundles.

2. **Identify the Types of Leaves**:
- There are two main types of flowering plants: dicots and monocots. Each has distinct characteristics regarding their leaf structure.

3. **Examine the Bundle Sheath in Dicot Leaves**:
- In dicot leaves, the bundle sheath is typically single-layered and consists of colorless cells. The extensions of the bundle sheath do not contain sclerenchyma.

4. **Examine the Bundle Sheath in Monocot Leaves**:
- In monocot leaves, the bundle sheath can be either single or double-layered. The cells in these layers often contain chloroplasts and can include sclerenchyma cells.

5. **Conclusion**:
- Sclerenchymatous patches as bundle sheath extensions are primarily found in the leaves of monocots. Therefore, the correct answer to the question is "monocots".

### Final Answer:
Sclerenchymatous patches as bundle sheath extensions are found in the leaves of **monocots**.
