Length of a plant increases due to the activity of

Options

A. apical meristem
B. reproductive meristem
C. secondary meristem
D. lateral meristem

Answer

**Step-by-Step Solution:**

1. **Identify the Meristems**: Understand that there are different types of meristems in plants, which are responsible for growth. The main types mentioned are Apical Meristem, Reproductive Meristem, Secondary Meristem, and Lateral Meristem.

2. **Focus on Apical Meristem**: The Apical Meristem is specifically located at the tips of roots and shoots. This is crucial for the vertical growth of the plant.

3. **Function of Apical Meristem**: The Apical Meristem is responsible for the increase in length of the plant. It is part of the primary meristem and is active during the early stages of the plant's life.

4. **Role in Plant Growth**: The cells in the Apical Meristem divide and differentiate to form new tissues, which contribute to the elongation of the plant, thereby increasing its height.

5. **Conclusion**: The length of a plant increases primarily due to the activity of the Apical Meristem, which is responsible for the vertical growth at the tips of the roots and shoots.

**Final Answer**: The length of a plant increases due to the activity of the Apical Meristem.
