B4.9 Rate of transpiration

Remember when you put the celery in the water? What happened to the water level by the next day?

• The level dropped A LOT, because the celery sucked it up.

• The level stayed the same, because the celery was dead.

• The level dropped a little, because of evaporation.

When we added red food coloring to the water, what did that prove?

• That the celery leaves caught the evaporating red water.

• That the celery was absorbing all the red water.

• That the water was passing through the celery all the way up to the leaves.
