Explanation:
Based on the information provided, the fact that cross sections of different areas of the same plant show cells with very different structures suggests that the cells in these two areas have different functions (Option C).
Different cell structures typically indicate specialized functions. Different areas of a plant may serve distinct purposes, such as leaf cells specializing in photosynthesis or root cells specializing in absorption of water and nutrients. The variations in cell structure reflect these functional differences in different plant regions.
