Eustele is the characteristic stele of

Options

A. dicot stem
B. monocot stem
C. monct root
D. none of these

Answer

To answer the question "Eustele is the characteristic stele of," we will follow these steps:

### Step 1: Understand the term 'Eustele'
Eustele refers to a specific type of vascular arrangement found in certain plants. It consists of vascular bundles that are arranged in a ring around the pith.

**Hint:** Remember that 'Eustele' is related to the arrangement of vascular tissues in plants.

### Step 2: Identify the types of plants
We need to differentiate between monocots and dicots, as well as roots and stems. Eustele is primarily associated with monocots.

**Hint:** Think about the characteristics of monocots and dicots, especially in terms of their vascular tissue arrangement.

### Step 3: Analyze the vascular bundles
In eustele, the vascular bundles are typically collateral, meaning that the phloem is located on one side of the xylem. In some cases, they can be bicollateral, where phloem is present on both sides of the xylem.

**Hint:** Focus on the arrangement of vascular bundles and their types (collateral vs. bicollateral).

### Step 4: Determine the correct answer
Since eustele is a characteristic feature of monocots, and it is absent in dicots, we conclude that the correct answer is that eustele is characteristic of monocot flowering plants.

**Hint:** Recall that monocots have a distinct vascular arrangement compared to dicots.

### Final Answer:
Eustele is the characteristic stele of monocot flowering plants.
