5% Salt Solution. 10% Salt Solution.9% Salt Solution . Procedure. Plant Cells in tap water . Prepare a wet mount of an Elodea leaf with tap water. To do this, use the forceps to place the leaf in the center of the flat side of the glass slide. Flatten the leaf as much as possible. Use the pipet to place one or two drops of distilled water onto the leaf so it is covered, as shown in Figure 1 ...

Prepare a second wet mount slide using another elodea leaf in 10% salt solution (NaCl, 10g/100mL). Place slide on microscope and view at 4X objective, then 10X objective. Focus slide on medium power. Locate cells along the edge of the leaf and notice the location of the chloroplasts in relation to the cell wall. Focus slide at 40X objective and draw cells in left circle below . Normal Elodea ...

Part 2: Elodea in water. 10% Salt Solution: Remove the slide from the stage of the microscope. Carefully place 2 drops of the 10% salt solution on the slide at the left at the left edge of the cover slip. Tear off a small piece of paper towel and place the torn edge on the slide at the right edge of the cover slip. The piece of towel should begin to soak up water, drawing the salt solution ...

Elodea in. 10 % salt solution.) Why did the cells shrink? (Higher salt concentration caused the diffusion of more water from within the cell to outside the cell.) Why didn't the salt from the outside just move inside the cell instead of the water moving out of the cell? What does this tell you about the cell membrane? (The cell membrane is selectively permeable. It allows the movement of water ...

the side where the salt solution was placed. The towel will begin to soak up water, drawing the salt solution under the cover slip . After you are sure the solution has been drawn under the cover slip, let the slide sit for 3 to 5 minutes in order for the cells to adjust. Observe the slide and record your observations with detailed diagrams as you did in step one. Be sure to clearly note (in ...
