In a plant, cell/tissues arising out of the same meristem have different structrue at maturity it is known as (A)______

Answer

To solve the question, we need to identify the term that describes the phenomenon where cells or tissues arising from the same meristem develop into different structures at maturity. Here’s a step-by-step breakdown of the solution:

### Step-by-Step Solution:

1. **Understanding Meristems**:
- Meristems are regions in plants where cells are actively dividing. These cells are undifferentiated and have the potential to develop into various types of cells and tissues.

2. **Cell Differentiation**:
- As the cells produced by meristems divide and grow, they undergo a process called differentiation. This is where the cells start to develop specific structures and functions.

3. **Maturation of Cells**:
- During maturation, the initially similar cells can develop into different types of cells or tissues. For example, cells from the same meristem can become part of leaves, stems, or roots, each with distinct structures and functions.

4. **Identifying the Term**:
- The phenomenon where cells or tissues from the same meristem develop different structures at maturity is referred to as "differentiation." Specifically, when the differentiation occurs from the same origin, it is termed "open differentiation."

5. **Filling in the Blank**:
- Therefore, the correct term to fill in the blank (A) in the statement is "open differentiation."

### Final Answer:
In a plant, cell/tissues arising out of the same meristem have different structures at maturity it is known as (A) **open differentiation**.
