1. What is osmosis? 2. Celery is composed of millions of plant cells. Do these cells contain any water?

3. Did the cut celery in step 8 & 9 show any color change that would indicate that the water did enter the celery cells?

4. If you placed the celery into a bottle of colored water that was 35% sugar, would the colored water be seen in the celery? Why or why not? (HINT: Drawing a diagram of this scenario may help – 35% sugar is a very concentrated solution…)
