Select the odd one w.r.t secondary meristem

Options

A. (a) intrafascicular cambium
B. (b) wound cambium
C. (c) interfascicular cambium
D. (d) cork cambium

Answer

To solve the question of selecting the odd one out with respect to secondary meristem, we can follow these steps:

### Step 1: Understand Secondary Meristem
- Secondary meristem is formed during secondary growth, which occurs after primary growth. It is permanent and derived from primary meristem.

**Hint:** Remember that secondary meristem is associated with growth that happens after the initial growth phase.

### Step 2: Identify Characteristics of Secondary Meristem
- Secondary meristem involves de-differentiation, where cells regain the ability to divide and lose their specific functions. This allows them to take on new roles.

**Hint:** Focus on the concept of de-differentiation to differentiate secondary meristem from other types.

### Step 3: Analyze the Given Options
- The options include intrafascicular cambium and possibly other types of meristems. We need to evaluate each option in relation to secondary meristem characteristics.

**Hint:** Compare each option to the properties of secondary meristem, especially the origin and function.

### Step 4: Evaluate Intrafascicular Cambium
- Intrafascicular cambium is formed during primary growth and is derived from embryonic meristem. It shows differentiation, which is the opposite of de-differentiation.

**Hint:** Note that the origin (primary growth vs. secondary growth) is crucial in determining the odd one out.

### Step 5: Conclusion
- Since intrafascicular cambium is formed during primary growth and is not a secondary meristem, it is the odd one out. The other options (not specified but implied to be secondary meristems) would share characteristics with secondary meristem.

**Final Answer:** The odd one out with respect to secondary meristem is **A) Intrafascicular Cambium**.
