Water cavity & V or Y- shaped xylum occurs in -

Options

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

Answer

To determine where water cavities and V or Y-shaped xylem occur, we need to analyze the characteristics of different plant structures. Here’s a step-by-step solution:

### Step 1: Understand the Structure of Xylem
Xylem is a type of vascular tissue responsible for the transport of water and nutrients in plants. It consists of various cell types, including tracheids and vessel elements, which can form different shapes.

### Step 2: Identify Water Cavities
Water cavities, also known as lissigenous cavities, are intercellular spaces formed through the dissolution of entire cells. These cavities can store water, gases, and sometimes oils. They are commonly found in certain plants, particularly in some monocots.

### Step 3: Examine the Types of Plants
- **Dicot Stem**: Typically has a ring of vascular bundles and does not usually exhibit V or Y-shaped xylem.
- **Monocot Root**: Generally has a different arrangement of vascular tissues and does not typically have water cavities.
- **Monocot Stem**: In monocot stems, xylem is located towards the inner side, and the vascular bundles are usually scattered. They can exhibit V or Y-shaped xylem.
- **Dicot Root**: Similar to dicot stems, they do not typically exhibit the characteristics in question.

### Step 4: Conclude on the Correct Option
Given that V or Y-shaped xylem and water cavities are characteristics associated with monocot stems, the correct answer is:

**Option C: Monocot Stem**

### Final Answer:
Water cavities and V or Y-shaped xylem occur in **monocot stems** (Option C).
