Plant cell wall consists of

Options

A. Lignin, hemicellulose , pectin and lipid
B. hemicellulose , pectin, protein, and lipid
C. Cellulose , hemicellulose, pectin and lignin
D. Cellulose, hemicellulose , tubulin and lignin

Answer

### Step-by-Step Solution:

1. **Understanding the Plant Cell Wall**: The plant cell wall is a rigid structure that surrounds the cell membrane, providing support and protection to the plant cell. It is primarily found in plants, algae, and some prokaryotes.

2. **Components of the Plant Cell Wall**: The plant cell wall is composed of several key components:
- **Cellulose**: This is the main structural component of the plant cell wall, providing strength and rigidity.
- **Hemicellulose**: This is a heteropolymer that works alongside cellulose to provide structural support and flexibility.
- **Pectin**: This is a polysaccharide that helps in cell wall expansion and is crucial for the growth of the plant.
- **Lignin**: This is a complex organic polymer that adds rigidity and waterproofing to the secondary cell wall, making it more durable.

3. **Analyzing the Options**: Given the options:
- a. Lignin, hemicellulose, protein, and lipid.
- b. Hemicellulose, pectin, protein, and lipid.
- c. Cellulose, hemicellulose, pectin, and lignin.
- d. Cellulose, hemicellulose, tubulin, and lignin.

We can see that option (c) includes all the correct components of the plant cell wall.

4. **Conclusion**: Based on the components identified, the correct answer to the question "Plant cell wall consists of" is option (c) - **Cellulose, Hemicellulose, Pectin, and Lignin**.
