Atactostele condition is found in the stem of

Options

A. dicots
B. monocots
C. ferns
D. pteridophytes

Answer

To determine where the atactostele condition is found in the stem, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Stele":**
- The term "stele" refers to the vascular tissue system located inside the endodermis of a plant. It includes the xylem and phloem, which are responsible for the conduction of water, nutrients, and food.

2. **Define Atactostele:**
- Atactostele is a specific arrangement of vascular bundles where they are scattered throughout the ground tissue of the stem. This contrasts with other arrangements where vascular bundles are organized in a specific pattern.

3. **Identify Vascular Bundle Arrangement:**
- In the atactostele condition, the vascular bundles are not arranged in a ring or any other organized structure but are instead distributed randomly within the stem's ground tissue.

4. **Examine Monocots vs. Dicots:**
- Monocots (like grasses and lilies) typically exhibit the atactostele condition, where vascular bundles are scattered.
- Dicots (like beans and sunflowers) exhibit a eustele condition, where vascular bundles are arranged in a circular pattern.

5. **Conclusion:**
- Based on the definitions and characteristics of the vascular arrangements, we conclude that the atactostele condition is found in the stem of monocots.

### Final Answer:
The atactostele condition is found in the stem of monocots.
