One of the main constituents of paper is a substance called 'cellulose' obtained from plant cells
based on the above statement, which of these parts of a plant cell would you say contributes towards the production of paper ?

Options

A. Cell membrane
B. Cell wall
C. Cytoplasm
D. Nucleus

Answer

To answer the question regarding which part of a plant cell contributes to the production of paper, we will analyze the options provided step by step.

### Step-by-Step Solution:

1. **Understanding the Question**: The question states that cellulose is a main constituent of paper and it is obtained from plant cells. We need to identify which part of the plant cell contributes to the production of cellulose.

2. **Analyzing the Options**:
- **Option 1: Cell Membrane**: The cell membrane is responsible for controlling the movement of substances in and out of the cell. It does not produce cellulose, so this option is not correct.

- **Option 2: Cell Wall**: The cell wall is primarily composed of cellulose. Since cellulose is the main constituent of paper, this option is correct. The cell wall provides structure and support to the plant and is where cellulose is found.

- **Option 3: Cytoplasm**: The cytoplasm is the gel-like substance within the cell that supports organelles. While it is essential for cell function, it does not contribute to the production of cellulose.

- **Option 4: Nucleus**: The nucleus contains genetic material and is involved in cell division and regulation. It does not play a role in the production of cellulose.

3. **Conclusion**: Based on the analysis of the options, the part of the plant cell that contributes to the production of paper is the **cell wall**, as it is made up of cellulose.

### Final Answer:
The part of a plant cell that contributes to the production of paper is the **cell wall**.
