Why cambium is considered as lateral meristem?

Options

A. Brcause it gives rise to lateral branches.
B. Because it increases the girth of a plant.
C. Because it increases the length of a plant.
D. None of these

Answer

**Step-by-Step Solution:**

1. **Understanding Cambium**: Cambium is a type of meristematic tissue found in plants. It plays a crucial role in the growth and development of the plant.

2. **Definition of Lateral Meristem**: Lateral meristems are responsible for the secondary growth of plants, which increases their girth or thickness. This is in contrast to apical meristems, which are responsible for the elongation of the plant.

3. **Function of Cambium**: The primary function of cambium is to increase the girth of the plant. It does this by producing new cells that contribute to the growth of the plant in a lateral direction.

4. **Radial Growth**: Cambium divides radially, meaning it produces new cells both inward (towards the center of the plant) and outward (towards the surface). This radial division is what allows the plant to grow thicker.

5. **Conclusion**: Since cambium is responsible for increasing the girth of the plant laterally (as opposed to vertically), it is classified as a lateral meristem.

6. **Final Answer**: Cambium is considered a lateral meristem because it increases the girth of the plant.
