Plain Water Experiment

Purpose:

How will salt and plain water affect plant cells?

Hypothesis

Clear water:

If you place carrots and celery in plain water they will become flaccid and then eventually start to loose its colour and pieces of the celery or carrots will fall off. I know this because the vegetables will continue absorbing water putting the vegetable in a hypotonic solution. Pieces of the vegetable could break off because the cells are not getting what they need. The cells need to create glucose and oxygen through photosynthesis when those cells no longer have a purpose they might break off. The vegetables will lose their colour I know this because when you covered the plants you took away their carbon dioxide, took away their source of sun, drowned
Fill the beaker with 300 ml of water

3.Label beaker A and B

4. Add salt to the beaker number one and place carrots and celery in each beaker

5. In your chart record what the carrots and celery look like
Cover both of your beakers with plastic wrap so that no air gets in.

7. Let your beaker sit for 5 days.

8. Record your observations
