Stems

We conducted an experiment to see how the stem of a celery plant might carry water from the roots to the leaves.  Take a look at our before and after pictures below.  It was great to be able to see the role that a stem provides for a plant.  We also noticed that the celery with food coloring did not look very healthy, while the one with just water looked healthy.  We wondered what food coloring might do to the insides of our bodies, if it makes the celery look so bad.
