Plant stems

We learnt about the parts of the plant and their jobs. One of the jobs of the stem is to transport the water and nutrients that the roots suck up form the soil to the other parts of the plant. To see this happening we have carried out an investigation using celery and food colouring.

We looked carefully at a piece of celery and discovered that it has tiny holes in it that we think help to transport the water and nutrients. We used magnifying glasses to see this more clearly.

We then put the stems of celery into pots with water and food colouring and have left them overnight to see what happens.

We made our own predictions based on our scientific knowledge. What do you think will happen?
