The cambium ring of roots resembles the cambium ring of stem in

Options

A. Its mode of function
B. Its origin from ground tissue
C. Its wavy outline
D. All of these

Answer

To answer the question, "The cambium ring of roots resembles the cambium ring of stem in," we need to analyze the characteristics of the cambium in both roots and stems.

### Step-by-Step Solution:

1. **Understand Cambium Function**: The cambium is a type of lateral meristem responsible for the secondary growth of plants. It produces secondary xylem (wood) and secondary phloem (bark).

2. **Identify Cambium in Roots**: In roots, the cambium is found between the xylem and phloem, contributing to the increase in girth of the root. It is derived from the pericycle and is responsible for the formation of new vascular tissues.

3. **Identify Cambium in Stems**: In stems, the cambium is located between the xylem and phloem as well. It is also responsible for secondary growth, allowing the stem to increase in thickness.

4. **Compare Origin**: The cambium in roots originates from the pericycle, while in stems, it is derived from the vascular bundles. This indicates a difference in origin.

5. **Compare Structure**: Both cambium rings in roots and stems are circular in structure, allowing for uniform growth around the plant.

6. **Compare Function**: The primary function of the cambium in both roots and stems is to facilitate secondary growth by producing secondary xylem and phloem.

7. **Conclusion**: Based on the analysis, the cambium rings of roots and stems resemble each other mainly in their function of forming secondary xylem and phloem.

### Final Answer:
The cambium ring of roots resembles the cambium ring of stem in their function of forming secondary xylem and secondary phloem.
