In'young dicot stem, cambium is -

Options

A. Single layered
B. 2 layered
C. Multilayered
D. Absent

Answer

**Step-by-Step Solution:**

1. **Understanding Cambium**: Cambium is a type of meristematic tissue found in plants. It is responsible for the secondary growth of stems and roots, allowing them to increase in thickness.

2. **Location of Cambium**: In a young dicot stem, the cambium is located between the xylem (the tissue responsible for water transport) and the phloem (the tissue responsible for nutrient transport).

3. **Structure of Cambium in Young Dicot Stem**: In young dicot stems, the cambium is typically a single layer of cells. This means that it consists of one layer of cambial cells that can divide to produce new xylem and phloem cells.

4. **Exclusion of Other Options**:
- Cambium is not two-layered or multi-layered in young dicot stems; such structures may develop during later stages of growth.
- Cambium is not absent in dicot stems, as it plays a crucial role in secondary growth.

5. **Conclusion**: Therefore, the condition of cambium in a young dicot stem is that it is single-layered.

**Final Answer**: The correct answer is option 1: single layered.
