Their walls (blue green) are thin, and their vacuoles are large and full of watery contents that did not stain. Nuclei were present in all cells, but because these cells were so large and the section (slice) was cut so thin, most nuclei were cut away during the preparation of this slide. One nudeus is still present (X 160). (B) Chlorenchyma cells from a leaf of privet. Because these cells are small and the section is thicker than that in (A), most cells still ave nudlei (red). The structures close to the wall (blue) are chloroplasts. The large white areas are intracellular spaces where the cells have pulled away from each other, permitting carbon dioxide to diffuse rapidly throughout the leaf (X160).

Question

Examine As Shown. Why do most parenchyma cells as shown lack nuclei, whereas most as shown do have nuclei? In the geranium for as shown, did the real cells lack nuclei, or did something happen to the nuclei as the tissue was sliced to make the microscope slide?
