under Light Microscopy Feature Plant Cell Elodea Animal Cell Cheek Epithelial Cell Wall Present rigid clearly visible Absent Cell Membrane Present inner to cell wall less distinct Present easily visible under high magnification Cytoplasm Present granular appearance Present granular appearance Nucleus Present large often centrally located Present relatively smaller often eccentrically located Chloroplasts Present numerous green oval structures Absent Vacuoles Present large central vacuole Present smaller numerous vacuoles if visible Other Organelles May observe some depending on magnification eg mitochondria faintly May observe some depending on magnification eg sometimes nucleus only Figure 1 Microscopic Images Insert representative images of Elodea and cheek epithelial cells showing key features mentioned in Table 1 Label key organelles II Organelle Function and Clinical Relevance 2 The observations made during the microscopy portion of the exercise should be
