To study the effect of lead ion on the activity of roots of mung bean seedlings, the experiment adopts five kinds of different concentration lead ion to treat with the mung bean seedling, The results show that the higher concentration lead ion treatment resulted in lower activity of mung bean seedlings roots, and lessen protoplasmic surface charge of roots and the rate of electrophoresis migration...
The estimation of the membrane voltage and the polarisation factor of biological cells provide a base for the study of bio-manipulation techniques, such as dielectrophoresis, electroporation or electrofusion. To model a biological cell, an ellipsoidal particle with an insulating membrane is sometimes employed, but due to the limitation of the confocal nature of the coordinate system, the membrane...
