Select the correct statement

Options

A. Absorption of water by seeds and dry wood are examples of facilitated diffusion
B. The apoplast is the system of interconnected protoplasts
C. Pinus seeds cannot germinate and establish without the presence of mycorrhizae
D. The translocation phloem is unidirectional whereas in the xylem it is bidirectional

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks to select the correct statement regarding the plant kingdom.

2. **Analyzing the Statements**:
- The first statement discusses the absorption of water by seeds in dry wood and claims it is facilitated diffusion, which is incorrect. Instead, it is imbibation.
- The second statement mentions the system of interconnected protoplasts, which is also incorrect as apoplasts have cell walls and protoplasts are not interconnected in that way.
- The third statement claims that pineapple seeds cannot germinate and establish without the presence of mycorrhiza. This statement is correct as mycorrhiza provides essential nutrients to the pineapple seeds.
- The fourth statement discusses translocation flow, stating that it is unidirectional in one case and bi-directional in another, which is misleading.

3. **Identifying the Correct Statement**: Among the analyzed statements, the third statement about pineapple seeds and mycorrhiza is the only one that holds true.

4. **Conclusion**: The correct statement is that pineapple seeds cannot germinate and establish without the presence of mycorrhiza.

**Final Answer**: The correct statement is that pineapple seeds cannot germinate and establish without the presence of mycorrhiza.
