to protect against disease to give structural support to contain the parts of the cell to help with cell division
I gave my students this multiple choice question: What is the main function of the cell wall in a plant cell?

Only one answer is correct among these 4 choices:
- to protect against disease
- to give structural support
- to contain the parts of the cell
- to help with cell division

Could you tell me which one is correct?

to give structural support
