Make-up Lab: Osmosis in an Onion Cell

SLIDE 2

This microscope slide is of red

nion cells sitting

in a bath of distilled water. It is viewed at medium power (100x). Draw these cells in the first circle on your lab paper. Label the cell walls and the large central vacuole (the pink/purple area).

SLIDE 3

This microscope slide is of red onion cells sitting in a bath

f 10% NaCl. It is

viewed at medium power (100x). Draw these cells in the 2nd circle on your lab

paper. Label the cell

walls and the large central vacuole (the pink/purple area). *Notice the size difference in the

vacuole. What

happened and why?

SLIDE 4

If you were to take the 2nd slide (the red onion in salt water) and add distilled water to the sample, what do you think would happen to the vacuole? Draw your prediction in the 3rd circle. Label it Figure 3: DI Water prediction. For magnification, write n/a. Under the drawing, write a description of what is happening and why. Then, answer all the lab questions.
