Sclerenchymatous bundle sheath around vascular bundles is seen in
(a) monocot leaf
(b) dicot leaf
(c) dicot stem
(d) monocot stem

Options

A. monocot leaf
B. dicot leaf
C. dicot stem
D. monocot stem

Answer

To solve the question regarding where sclerenchymatous bundle sheath around vascular bundles is seen, we can follow these steps:

### Step 1: Understand the Structure
Sclerenchyma is a type of plant tissue that provides support. It is characterized by thick, lignified walls and is usually dead at maturity. In the context of vascular bundles, a sclerenchymatous bundle sheath refers to a layer of sclerenchyma cells that surrounds the vascular bundles.

### Step 2: Identify the Options
The options provided are:
(a) monocot leaf
(b) dicot leaf
(c) dicot stem
(d) monocot stem

### Step 3: Analyze Each Option
- **Monocot Leaf**: In monocot leaves, the vascular bundles are typically surrounded by parenchyma cells rather than sclerenchyma. Therefore, this option is unlikely.

- **Dicot Leaf**: Dicot leaves generally do not have a sclerenchymatous bundle sheath around their vascular bundles. This option can also be ruled out.

- **Dicot Stem**: Similar to dicot leaves, dicot stems do not typically feature a sclerenchymatous bundle sheath. This option is not correct.

- **Monocot Stem**: In monocot stems, vascular bundles are often surrounded by a sclerenchymatous bundle sheath. This is a common feature in monocots, where the vascular bundles are enclosed by a layer of sclerenchyma cells, providing structural support.

### Step 4: Conclusion
Based on the analysis, the correct answer is:
**(d) monocot stem**
