Pick out the correct statement from the following .

Options

A. The parenchyma cells undergo differnetiation during plant tissue culture
B. The tissues arising out of same meristem have always same structures at maturity
C. The products of meristematic cells retain the power of cell division by redifferentiation
D. Epidermins is a product of differentiation

Answer

To solve the question of identifying the correct statement from the given options, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze the First Statement:**
- **Statement:** "Parankaima cells undergo differentiation during plant tissue culture."
- **Explanation:** Parenchyma cells are in a totipotent state during plant tissue culture, meaning they can divide and proliferate without differentiating. Therefore, this statement is incorrect.

2. **Analyze the Second Statement:**
- **Statement:** "The tissues arising out of the same meristem have always the same structure."
- **Explanation:** Tissues that arise from the same meristem can have different structures at maturity depending on their location and function. For example, root cap cells and root epidermal cells arise from the same meristem but have different structures and functions. Hence, this statement is also incorrect.

3. **Analyze the Third Statement:**
- **Statement:** "The products of meristematic cells retain the power of cell division by re-differentiation."
- **Explanation:** The products of meristematic cells do not retain the power of division through re-differentiation. Instead, they retain the ability to divide through de-differentiation. Therefore, this statement is incorrect as well.

4. **Analyze the Fourth Statement:**
- **Statement:** "Epidermis is a product of differentiation."
- **Explanation:** The epidermis is indeed formed from the protoderm during the differentiation process in the development of the primary plant body. This statement is correct.

### Conclusion:
The correct statement is: **"Epidermis is a product of differentiation."**
