Select incorrect statement from the following.

Options

A. Vascular cambium and cork cambium are example of lateral
meristem
B. In dicot stems, endodermis is also referred as starch sheath
C. Bark refers to all the tissue outside of the vascular cambium and is a non-technical term.
D. In a dicot root, vascular cambium completely primary in origin

Answer

To solve the question of selecting the incorrect statement from the provided options, we will analyze each statement step by step.

### Step 1: Analyze the First Statement
**Statement:** The vascular cambium and the cork cambium are examples of lateral meristem.

**Analysis:**
- Vascular cambium is a type of meristematic tissue that is responsible for the production of xylem and phloem, which are essential for the conduction of water and nutrients in plants.
- Cork cambium is also a lateral meristem that produces cork cells, forming part of the protective outer layer of the plant.
- Both are indeed classified as lateral meristems, which contribute to the increase in girth of the plant.

**Conclusion:** This statement is correct.

### Step 2: Analyze the Second Statement
**Statement:** In dicot stem, the endodermis is referred to as Tarsier.

**Analysis:**
- The endodermis is the innermost layer of the cortex in the dicot stem and is often referred to as the starch sheath due to its starch storage.
- The term "Tarsier" does not relate to the endodermis in botanical terminology. This appears to be a misnomer or incorrect term.

**Conclusion:** This statement is incorrect.

### Step 3: Analyze the Third Statement
**Statement:** The bark refers to the tissue outside the vascular cambium.

**Analysis:**
- Bark is indeed defined as all the tissues that lie outside the vascular cambium, including the secondary phloem and periderm.
- This definition is widely accepted in botany.

**Conclusion:** This statement is correct.

### Step 4: Analyze the Fourth Statement
**Statement:** In dicot root, vascular cambium is completely primary in origin.

**Analysis:**
- In dicot roots, the vascular cambium is formed from the pericycle, which is a secondary growth tissue. Thus, the vascular cambium in dicot roots is secondary in origin, not primary.
- This statement contradicts the established understanding of plant anatomy.

**Conclusion:** This statement is incorrect.

### Final Conclusion
After analyzing all the statements, we find that:
- The second statement (regarding the endodermis being referred to as Tarsier) and the fourth statement (regarding the vascular cambium being completely primary in origin) are incorrect.
- However, since the question asks for a single incorrect statement, the fourth statement is the most clearly incorrect based on the context provided in the video.

### Answer: Option 4 is the incorrect statement.
