The correct Answer is:
### Step-by-Step Solution: 1. **Understanding the Question**: The question asks which structures provide mechanical support to the cell. 2. **Identifying the Structures**: The two main structures that can provide mechanical support are the cell wall and the cytoskeleton. 3. **Cell Wall**: - The cell wall is a rigid structure that forms the outer covering of the plasma membrane. - It is present in plants and fungi. In plants, the cell wall is primarily made of cellulose, while in fungi, it is made of chitin. - The functions of the cell wall include: - Providing shape to the cell. - Protecting the cell from injury. - Facilitating cell-to-cell interaction. - Providing mechanical support. 4. **Cytoskeleton**: - The cytoskeleton is an elaborate network of proteinaceous structures found in the cytoplasm. - It consists of various filaments and tubules that play a crucial role in maintaining the cell's shape. - The functions of the cytoskeleton include: - Providing mechanical support to the cell. - Facilitating cell motility (movement). - Maintaining the overall shape of the cell. 5. **Conclusion**: Since both the cell wall and the cytoskeleton provide mechanical support to the cell, the correct answer is that mechanical support to the cell is provided by both the cell wall and the cytoskeleton. ### Final Answer: Mechanical support to the cell is provided by both the cell wall and the cytoskeleton.
