Beakman explains how plants take up water through the xylem. To demonstrate this, he splits the stem of a white flower in half and puts each half into a different jar of colored water. He also puts a stick of celery in one of the jars. The next day, you can see the white flower is now two different colors and if you split the celery, you can see the xylem because it's now colored.
Bill Nye narrates the story of how photosynthesis was discovered. He explains the hypothesis of the experiment that shed light on how plants generate energy.
Beakman explains how leaves lose chlorophyll using a cartoon video. Then he explains the role of chlorophlyll in photosynthesis verbally. To further demonstrate, Beakman acts like the "chef" chlorophyll that provides food for the plant.
Hank explains in-depth the series of reactions that take place for a plant to produce food for itself, also known as photosynthesis. This video also explores the prerequisites (sunlight, carbon dioxide, and water) of these reactions.
