All During formation of leaves and elongation of stem, some cells 'left behind' from the shoot apical meristem, constitute ______

Options

A. Lateral meristem
B. Axillary bud
C. Cork cambium
D. Fascicular cambium

Answer

To solve the question, "During formation of leaves and elongation of stem, some cells 'left behind' from the shoot apical meristem, constitute ______", we can follow these steps:

### Step 1: Understand the Role of Shoot Apical Meristem
The shoot apical meristem (SAM) is a region of actively dividing cells located at the tip of the shoot. It is responsible for the growth of the plant in length and the formation of new leaves and flowers.

**Hint:** Recall that the shoot apical meristem is crucial for the vertical growth of the plant.

### Step 2: Identify the Cells Left Behind
As the shoot apical meristem produces new cells for leaf and stem elongation, some of these cells do not continue to divide and instead differentiate into other types of tissues or structures.

**Hint:** Think about what happens to the cells that are produced but not used for immediate growth.

### Step 3: Recognize the Types of Meristems
The cells that are left behind can develop into different types of meristems. The options provided are:
- Lateral meristem
- Axillary bud
- Cork cambium
- Fascicular cambium

**Hint:** Consider which of these options is specifically related to the growth of branches or flowers.

### Step 4: Determine the Correct Answer
The correct answer is **B: Axillary bud**. The axillary bud is formed from the cells left behind by the shoot apical meristem and can develop into branches or flowers.

**Hint:** Remember that axillary buds are located in the leaf axils and can give rise to new shoots or flowers.

### Final Answer
The answer to the question is **Axillary bud**.
