Select the incorrect statement.

Options

A. Vascular bundle of dicot stem said to be open
B. Intrafascicular cambium is primary lateral meristem.
C. All tissues lying inside the vascular cambium are called bark.
D. In dicot stem endodermis is referred as starch sheath

Answer

To solve the question, we need to analyze each of the statements provided and identify which one is incorrect.

### Step-by-Step Solution:

1. **Statement 1**: "Vascular bundles of Dicot stem are said to be open."
- **Analysis**: This statement is correct. In dicot stems, the vascular bundles are open because they contain cambium, which allows for secondary growth.

2. **Statement 2**: "Intrafasicular cambium is a primary lateral meristem."
- **Analysis**: This statement is also correct. Intrafasicular cambium is indeed a type of lateral meristem found between the xylem and phloem in vascular bundles, contributing to secondary growth.

3. **Statement 3**: "All tissues lying inside the vascular cambium are called bark."
- **Analysis**: This statement is incorrect. The term "bark" refers to all tissues outside the vascular cambium, including the phloem and periderm. The tissues inside the vascular cambium are referred to as the "wood" or "xylem."

4. **Statement 4**: "In dicot stem, endodermis is referred to as starch sheath."
- **Analysis**: This statement is correct. The endodermis in some plants can serve as a starch sheath, particularly in roots, where it may store starch.

### Conclusion:
The incorrect statement is: "All tissues lying inside the vascular cambium are called bark."
