Water containing cavities in vascular bundles are found in

Options

A. Maize
B. Cycas
C. Pinus
D. Sunflower

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the presence of water-containing cavities in vascular bundles. We need to identify which type of plant structure contains these cavities.

2. **Identifying Plant Types**: There are two main types of flowering plants: monocots (monocotyledons) and dicots (dicotyledons). We need to determine which of these types contains the water cavities in their vascular bundles.

3. **Characteristics of Monocots**: Monocots typically have closed vascular bundles. This means that there is no cambium layer present between the xylem and phloem. In monocots, the vascular bundles are often scattered throughout the stem and leaves.

4. **Formation of Water Cavities**: In monocots, some xylem cells can become non-functional over time. When this happens, water can accumulate in these spaces, forming cavities filled with water. These cavities do not facilitate the upward movement of water but serve as storage.

5. **Examples of Plants**: The question provides options including Sunflower, Pinus, Cycas, and Maize. Sunflower, Pinus, and Cycas are all dicots, which do not typically have these water cavities in their vascular bundles. Maize, on the other hand, is a monocot.

6. **Conclusion**: Since water-containing cavities in vascular bundles are found in monocots, the correct answer to the question is **Maize**.

**Final Answer**: Water containing cavities in vascular bundles are found in **Maize** (a monocot).
