Removal of cork from the trees is to be done with care. Otherwise the tree can die. This is because

Options

A. The xylem layer transporting water and minerals can be damaged
B. The primary rays giving strength can be damage
C. The inner pith with storage cells can damaged
D. The phloem used in transporting the sugars can be damaged

Answer

To understand why the removal of cork from trees must be done with care, let's analyze the options provided in the question step by step.

### Step-by-Step Solution:

1. **Understanding Cork and Its Role**:
- Cork is a protective layer that covers the outer part of the tree. It is made up of dead cells that provide insulation and protection against physical damage and pathogens.

2. **Identifying the Layers of the Tree**:
- Beneath the cork layer, there are several important layers, including the phloem and xylem. The phloem is responsible for transporting sugars produced by photosynthesis from the leaves to other parts of the plant.

3. **Analyzing the Options**:
- **Option A**: The xylem layer transporting water and minerals can be damaged.
- While the xylem is important, the question specifically relates to the removal of cork, which primarily affects the phloem.
- **Option B**: The primary rays giving strength can be damaged.
- This option is less relevant as the primary rays are not directly affected by cork removal.
- **Option C**: The inner pit with storage cells can be damaged.
- This is also not directly related to the cork removal process.
- **Option D**: The phloem used in transporting sugars can be damaged.
- This is the most relevant option. If the cork is removed carelessly, it can damage the phloem, disrupting the transport of sugars.

4. **Conclusion**:
- The correct answer is **Option D**. The removal of cork can damage the phloem, which is crucial for transporting sugars. If the flow of sugars is interrupted, the roots may starve, leading to the death of the tree.
