Which tissue is not correctly related to its fate during the secondary growth ?

Options

A. `{:("Tissue","Fate during secondary growth"),("Secondary xylem","Produced in high amount"):}`
B. `{:("Tissue","Fate during secondary growth"),("Primary phloem","Produced in low amount"):}`
C. `{:("Tissue","Fate during secondary growth"),("Cambial ring ","Cut off secondary permanenet tissue on both side "):}`
D. `{:("Tissue","Fate during secondary growth"),("Secondary phloem","Synthesized on outer side"):}`

Answer

To solve the question regarding which tissue is not correctly related to its fate during secondary growth, we need to analyze the options provided in the context of secondary growth in plants.

### Step-by-Step Solution:

1. **Understanding Secondary Growth**:
- Secondary growth refers to the increase in the girth of the plant, which occurs after the primary growth (increase in length).
- This growth is primarily facilitated by the cambium, a type of meristematic tissue.

2. **Role of Cambium**:
- Cambium is responsible for producing secondary vascular tissues. It forms a cambial ring that divides to produce new cells on both sides.
- The cells produced on the inner side differentiate into secondary xylem (wood), while those on the outer side differentiate into secondary phloem.

3. **Formation of Secondary Tissues**:
- **Secondary Xylem**: This is formed on the inner side of the cambium and contributes to the wood of the plant.
- **Secondary Phloem**: This is formed on the outer side of the cambium and is involved in transporting nutrients.

4. **Cork Cambium**:
- Cork cambium is another type of cambium that forms in the outer layers of the plant. It produces cork cells on the outside and secondary phloem on the inside.

5. **Analyzing the Options**:
- We need to identify the option that incorrectly describes the fate of a tissue during secondary growth.
- If an option states that secondary phloem is formed on the outer side during secondary growth, it is incorrect because cork cambium produces cork on the outer side, while secondary phloem is produced on the inner side.

6. **Conclusion**:
- The incorrect relationship is that secondary phloem is formed on the outer side during secondary growth. This is not true as cork is formed on the outer side, while secondary phloem is formed on the inner side.

### Final Answer:
The tissue that is not correctly related to its fate during secondary growth is the secondary phloem, which is incorrectly stated to be formed on the outer side.
