A Fun Plant Experiment to Try at Homel!
Without water, plants would die. Do you know how water gets from the roots of a plant to the rest of the plant? The water travels through tiny tubes that from pathways to all parts of the plant. This is similar to how blood flows in our bodies. And here is an experiment to prove it.
Materials
a celery stick
a sharp knife
a glass of water
some red food colour
___60___
1)Put a few drops of the red food colour in the glass of water.
2)Cut the bottom of the celery stick and place the celery in the water.
3)Leave the celery stick in the glass of water for several hours.
4)Remove the celery stick and cut it into pieces horizontally, that is, across the stem(茎). Observation
Red food colour is present in all cross sections from the bottom of the celery stick right up to the leaves.
Explanation
The water, along with the red food colour, has been transported up the celery stick through the tiny tubes in it. The experiment, therefore, proves that tiny tubes in plants enable water to reach all parts of the plant. The red food colour shows where the watger has travelled to in the celery stick.
