_________Surrounds the cell membrane and is an important part of plant cells as plants do not have skeleton for protection and support

Options

A. Chitin
B. Cellulose
C. Cytoplasm
D. protoplasm

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the material that surrounds the cell membrane in plant cells and provides support, as plants do not have a skeleton.

2. **Identifying the Options**: The options given are:
- Chitin
- Cellulose
- Cytoplasm
- Protoplasm

3. **Analyzing Each Option**:
- **Chitin**: This is a structural component found in the cell walls of fungi, not in plants.
- **Cellulose**: This is a polysaccharide that forms the primary component of the cell wall in plant cells, providing structure and support.
- **Cytoplasm**: This is the fluid inside the cell where organelles are suspended; it does not surround the cell membrane.
- **Protoplasm**: This refers to the living contents of a cell, including the cytoplasm and nucleus, but it does not specifically refer to the structure surrounding the cell membrane.

4. **Choosing the Correct Answer**: Based on the analysis, the correct answer is **Cellulose**, as it is the material that surrounds the cell membrane in plant cells and provides necessary support.

5. **Final Answer**: Cellulose surrounds the cell membrane and is an important part of plant cells as plants do not have a skeleton for protection and support.
