Do plants need leaves to grow?

In our science lesson on Friday we talked in talk partners about what a plant needed to grow healthily. We said that plants need leaves to take in light. Plants use this light to make food.

To investigate if this is true we set up the experiment shown above. On one plant we took off all the leaves. On the other plant, we left all the leaves on. To make the test fair, we kept everything else the same.

We will leave this set up for two weeks and then observe (see) which plant looks healthier.
