What is A and B respectively ?

Options

A. A - out side
B - secondary xylem
B. A - Inner side
B - secondary xylem
C. A - Inner side
B - secondary phloem
D. A - outer side
B - secondary phloem

Answer

To solve the question regarding the activity of the vascular cambium, we will break it down into steps.

### Step-by-Step Solution:

1. **Understanding Vascular Cambium**:
- The vascular cambium is a type of lateral meristematic tissue found in plants. It is responsible for the production of secondary growth, which increases the thickness of stems and roots.

2. **Activity of Vascular Cambium**:
- The vascular cambium is known to be more active on one side compared to the other. This is due to its role in producing secondary tissues.

3. **Identifying Side of Activity**:
- The cambium is generally more active on the inner side of the plant. This means that it produces more cells towards the interior of the plant structure.

4. **Products of Vascular Cambium**:
- The primary products of the vascular cambium are secondary xylem and secondary phloem. However, it is known that the cambium produces more secondary xylem than secondary phloem.

5. **Final Answers**:
- Therefore, for the question:
- A (the side where the cambium is more active) is "inner side".
- B (the product that is produced more) is "secondary xylem".

### Conclusion:
- The answer to the question is:
- A: Inner side
- B: Secondary xylem
