Meristem present at Lamina margin is :-

Options

A. Apical meristem
B. Intercalary meristem
C. Mass meristem
D. Marginal meristem

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
- The question asks about the type of meristem that is present at the lamina margin of a leaf.

2. **Identifying the Options:**
- The options provided are:
- a) Apical meristem
- b) Intercalary meristem
- c) Mass meristem
- d) Marginal meristem

3. **Defining Each Type of Meristem:**
- **Apical Meristem:** This is found at the tips of roots and shoots. It is responsible for the primary growth of the plant, allowing it to grow taller or deeper.
- **Intercalary Meristem:** This type is located at the base of leaves or internodes, particularly in monocots like grasses. It allows for rapid growth and elongation of these parts.
- **Mass Meristem:** This type divides in multiple planes and contributes to the formation of various tissues such as cortex and pith.
- **Marginal Meristem:** This is located along the margins of the leaf primordium and is responsible for the formation of the leaf blade.

4. **Analyzing the Options:**
- Since the question specifically asks about the meristem at the lamina margin, we can eliminate the apical, intercalary, and mass meristems as they do not fit this description.

5. **Conclusion:**
- The correct answer is **Marginal Meristem**, as it is specifically located at the margins of the leaf and is responsible for the development of the leaf blade.

**Final Answer:**
The meristem present at the lamina margin is **Marginal Meristem**.
