Lysigenous cavities present in vascular bundles of

Options

A. Monocot stem
B. Dicot root
C. Dicot
D. Dicot leaf

Answer

**Step-by-Step Solution:**

1. **Understanding Lysigenous Cavities:**
- Lysigenous cavities are specialized structures that form within the vascular bundles of plants. They are essentially spaces or cavities that develop due to the dissolution of certain cells.

2. **Formation of Lysigenous Cavities:**
- These cavities are formed when protoxylem vessels and parenchyma cells undergo dissolution. As these cells break down, they create empty spaces filled with water, which are referred to as lysigenous cavities.

3. **Identifying the Location:**
- Lysigenous cavities are specifically found in the vascular bundles of plants, which consist of xylem and phloem tissues.

4. **Determining the Plant Type:**
- The question asks about the presence of lysigenous cavities in vascular bundles. It is important to note that these cavities are primarily observed in monocots, particularly in the stems of monocotyledonous plants.

5. **Evaluating the Options:**
- The options provided are:
1. Monocot stem
2. Dicot root
3. Dicot
4. Dicot leaf
- Based on the understanding that lysigenous cavities are found in monocots, particularly in their stems, we can conclude that the correct answer is **monocot stem**.

6. **Final Answer:**
- Therefore, the correct answer to the question "Lysigenous cavities present in vascular bundles of" is **monocot stem**.
