Lateral meristem is present in

Options

A. vascular cambium
B. cork cambium
C. xylem and phloem
D. both(1)(2)

Answer

To answer the question "Lateral meristem is present in," we can follow these steps:

### Step 1: Understand what lateral meristem is
- Lateral meristem is a type of meristematic tissue that is responsible for the secondary growth in plants. It is located on the lateral sides of stems and roots.

### Step 2: Identify the types of lateral meristem
- The two main types of lateral meristem are:
1. **Vascular cambium**: This lateral meristem is responsible for the formation of secondary vascular tissues (xylem and phloem).
2. **Cork cambium**: This lateral meristem produces cork cells, which contribute to the outer protective layer of the plant.

### Step 3: Analyze the options provided
- **Option A: Vascular cambium** - This is indeed a type of lateral meristem.
- **Option B: Cork cambium** - This is also a type of lateral meristem.
- **Option C: Xylem and phloem** - These are not meristems; they are the tissues produced by the vascular cambium.
- **Option D: Both A and B** - This option correctly identifies both types of lateral meristem.

### Step 4: Conclude the answer
- Since both vascular cambium and cork cambium are examples of lateral meristem, the correct answer is **D: Both A and B**.
