Parenchymal Cells are associated with which plant family in this material?

• A. Lamiaceae
• B. Pinaceae
• C. Piperaceae
• D. Rosaceae

Answer: (C)

Parenchyma is the basic living tissue that forms the bulk of many plant organs, and its appearance and where it sits in the tissue can help identify a plant family on microscopy slides. In the material you're studying, the Piperaceae examples show a ground tissue dominated by thin-walled parenchyma cells arranged in a loose matrix with visible intercellular spaces, a pattern used as a diagnostic cue for that family. Because this specific parenchyma arrangement is highlighted for Piperaceae in the slides, it’s the best match among the given options. The other families in the material don’t display this same parenchyma pattern in the contexts shown, so they aren’t the correct associations here.
