Key Observation When we first added Paramecium into 225 ml of Dryl’s solution inside the electrophoresis chamber, the movement of Paramecium was slow and moved all over the place. After we turned on the power supply, the movement of Paramecium became faster and the paramecium moved linearly. The speed of Paramecium before turning the power on was 2.67 mm/sec and after the power on, the speed went up to 5 mm/sec.

Hypothesis When 40 ml of BaCl gets added to the Dryl’s solution, the Paramecium Tetraurelia cells will swim slower as the Paramecium is sensitive to Salt and will try to swim to find a better environment but will soon slow down as salt diffuses in and out the cell membrane.
