| Abstract: | This article mainly deals with the effect of Cr 6 pollution on the ultramicroscopic structure of Nuclei, Mitochondria, Golgi apparatus, Palisade tissue, plasmolysis in top stem cell of Brasenia schreberi Gmel. The results of damaging effect of Cr 6 pollution on Brasenia schreberi Gmel showed that the form of Nuclei changed, Mitochondria ruptured or budded, Golgi apparatus slacked or disappeared, Proplastid ruptured, the structure of Palisade tissue damaged, the volume of starch in Palisade tissue increased greatly, plasmolysis took place in cell and, these affected cell's function in all and finally damadged or destroyed the cell. |
