The diagram shows the main structures of an animal cell and a plant cell with labels for the nucleus, cell membrane, cytoplasm, mitochondria, cell wall, chloroplast, and vacuole.
Explain why the cell wall is important for a plant cell (as shown in the diagram).
Show answer, mark scheme and Mentor explanation
MP1: Provides strength/support to the cell.
MP2: Helps the cell keep its shape (prevents the cell bursting when water enters).
Can you spot the two ideas the mark scheme needs here?
This question is testing whether you can explain the importance of the plant cell wall using both required mark-scheme points. One mark comes from saying that the cell wall gives the cell strength or support. The other mark comes from explaining that it helps the cell keep its shape, including preventing the cell bursting when water enters. To secure every mark, your answer needs both ideas, not just a general statement that the cell wall is important.
