Investigate the evidence

Use these descriptions of the three microscope views: View A shows onion epidermis cells packed closely in orderly rows. The cells are rectangular, have clearly defined cell walls, and show nuclei. View B shows leaf cells with clearly defined cell walls, many green chloroplasts, and visible nuclei. View C shows cells with irregular outlines, no visible cell walls or chloroplasts, and visible nuclei. A visible feature is an observation; using that feature to decide what kind of cell it is, is an inference.
