Select the incorrect pair.

Options

A. Cell wall - Structural support
B. Central vacuole - Storage
C. Amyloplast - Starch storage
D. Plasmodesmata - Protection

Answer

To solve the question of selecting the incorrect pair, we will analyze each option provided and determine their correctness based on biological concepts related to cell structure and function.

### Step-by-Step Solution:

1. **Understand the Function of Cell Wall**:
- The cell wall provides structural support to the cell. It helps maintain the shape of the cell and withstands turgor pressure from the internal water content.
- **Conclusion**: The statement "Cell wall acts as structural support" is **correct**.

2. **Examine the Role of Central Vacuole**:
- The central vacuole is primarily involved in the storage of substances such as water, nutrients, and waste products. It plays a crucial role in maintaining turgor pressure in plant cells.
- **Conclusion**: The statement "Central vacuole acts as storage" is **correct**.

3. **Analyze the Function of Amyloplast**:
- Amyloplasts are a type of plastid that stores carbohydrates in the form of starch. They are a specialized type of leukoplast.
- **Conclusion**: The statement "Amyloplast acts as starch storage" is **correct**.

4. **Evaluate the Function of Plasmodesmata**:
- Plasmodesmata are microscopic channels that traverse the cell walls of plant cells, allowing for communication and transport of materials between adjacent cells. They do not provide protection.
- **Conclusion**: The statement "Plasmodesmata acts as protection" is **incorrect**.

5. **Identify the Incorrect Pair**:
- Based on the analysis, the only incorrect statement is regarding plasmodesmata, which do not serve a protective function but rather a communicative one.
- Therefore, the answer to the question is **option D**: Plasmodesmata - Protection.

### Final Answer:
The incorrect pair is **option D: Plasmodesmata - Protection**.
