both a dicot root and monocot root possess six vascular bundles.the two can be distinguished by

Options

A. presence of lysigenous cavity in monocot root
B. occurrence of more metaxylem vessels in dicot root
C. presence of exarch condition in monocot root
D. outline of vessels.

Answer

To distinguish between a dicot root and a monocot root that both possess six vascular bundles, follow these steps:

### Step-by-Step Solution:

1. **Understanding Vascular Bundles**: Both dicot and monocot roots can have six vascular bundles. Vascular bundles are essential for the transport of water, nutrients, and food within the plant.

2. **Identifying Key Differences**: The main differences between dicot and monocot roots lie in their structure and arrangement of vascular tissues.

3. **Examining the Outline of Vessels**: One of the most significant distinguishing features is the outline of the vessels. In dicot roots, the vessels tend to have a more rounded or oval shape, while in monocot roots, the vessels are usually more angular or irregular in shape.

4. **Considering Other Factors**: While there are other characteristics such as the presence of lysogenous cavities or the number of metaxylem vessels, these are not the primary distinguishing features when both types of roots have the same number of vascular bundles.

5. **Conclusion**: The correct way to distinguish between a dicot root and a monocot root, when both have six vascular bundles, is by examining the outline of the vessels.

### Final Answer:
The two can be distinguished by the outline of vessels.
