Presentation transcript:

 There has been an experiment conducted by K. S. Rathore and A. Goldsworthy and they applied direct current of about a millionth of an ampere to cells of tobacco plants. The plants grew callus other than normal cells. It became noticeable after ten days and was very obvious by the twenty-second day. ''The effect was dependent on the direction of the current,'' the scientists reported. When the callus was negative the growth rate stimulated by seventy percent and then it was reversed, it was “slightly inhibitory”. it was concluded that although normal cells did not grow due to the electricity, there was a different kind of growth. So the electricity had an effect on the plant.

 A beet, also known as garden beet, blood turnip or red beet is a vegetable with much vitamin A and vitamin C. This experiment will observe the reactions on beet plant cells when different amounts of electricity are added to them. From the review of research, it has been discovered that the phloem tissues contain cells that transport sugars and nutrition to the places where growth is occurring in the plant (Spanswick 2006). So as the beet is electrocuted, the cells will release glucose into the water and it will be measured with Other experimenters concluded that the plant will brown Glucose Test Strips to observe whether the different voltages caused more glucose to be released.

CONTROL

 The purpose of this experiment was to prove that the higher the voltage added to a beet, the more glucose released into the water. In the experiment, the higher the voltage, the more glucose was released from the cell membranes. The lowest amount of voltage released the lowest amount of glucose. The experiment supported the hypothesis because the higher voltage released the most glucose from the cell membranes and vice versa. It would be helpful to have higher amounts of electricity added to the beets.
