Figure 1. Microscopic view of onion cells prior to the experiment. The onion cell is composed primarily of water. The cell wall and cell membrane are not clear because of the high water concentration between the membranes.Figure 2. The onion cell with salt. The cell wall of the cell is shriveled. The cell membrane started to separate from the cell wall, leading to plasmolysis.

Figure 3. The precipitated DNA. This is a picture of the test tube with the DNA after the ethanol was dropped in it. The DNA is visible and appears cloudy on the top of the test tube.
