Cell wall of plant cell is

Options

A. semi-permeable
B. selectively permeable
C. fully permeable
D. impermeable.

Explanation

**Step-by-Step Solution:**

1. **Understanding Cell Wall Functionality:**
The cell wall of a plant cell is a crucial structure that surrounds the cell membrane. It provides support and protection to the plant cell.

2. **Defining Permeability:**
Permeability refers to the ability of a membrane to allow substances to pass through it. There are different types of permeability:
- **Semi-permeable:** Allows only certain substances to pass.
- **Selectively permeable:** Similar to semi-permeable but can actively control what passes through.
- **Fully permeable:** Allows all substances to pass through without restriction.
- **Impermeable:** Does not allow any substances to pass through.

3. **Analyzing the Plant Cell Wall:**
The plant cell wall is composed of cellulose and other polysaccharides, which create a structure that permits the passage of both solvent (like water) and solute (like nutrients and minerals) molecules.

4. **Conclusion on Permeability of Plant Cell Wall:**
Since the plant cell wall allows both solvent and solute molecules to pass through freely, it can be classified as fully permeable.

5. **Final Answer:**
Therefore, the correct answer to the question "Cell wall of plant cell is" is **option C: fully permeable.**
