vascular bundles of monocot stem are

Options

A. Schizolysigenous water cavity
B. V or Y shaped xylem
C. Sclerenchymatous bundle sheath
D. Sclerenhymatous hypodermis

Answer

**Step-by-Step Solution:**

1. **Understanding Vascular Bundles:**
- Vascular bundles are the structures that contain xylem and phloem, which are responsible for the transport of water, nutrients, and food in plants.

2. **Characteristics of Monocot Stems:**
- In monocot stems, vascular bundles are typically scattered throughout the stem rather than arranged in a circle, which is common in dicots.

3. **Types of Water Cavities:**
- The question mentions "sciogenous" and "lysigenous" water cavities.
- Sciogenous cavities are formed by the separation of cells, creating intercellular spaces, while lysigenous cavities are formed by the breakdown of cell walls and protoplasm.

4. **Evaluating the Options:**
- **Option A (Sciogenous water cavity):** This is incorrect for monocot stems as they contain lysigenous cavities.
- **Option B (V or Y shaped xylem):** This is also incorrect; monocot xylem does not typically have this shape.
- **Option C (Sclerenchymatous bundle sheath):** This is correct. Monocot stems have a bundle sheath made of sclerenchyma, providing support.
- **Option D (Sclerenchymatous hypodermis):** This is also correct. The outer layer of monocot stems often consists of sclerenchyma for additional support.

5. **Conclusion:**
- The correct answers regarding the vascular bundles of monocot stems are options C and D.
