Science Question of the Week: Hydroponic Inquiry
How does water move through plants? Water is polar molecule, meaning one side is more positively charged and the other side is more negatively charged. This causes water molecules to stick to themselves, through cohesion, and also stick to different molecules, through adhesion. So, the water is able to travel through the veins of the plants, called xylem. As you can see from the pictures, the blue water travelled all the way to the top of the celery, from the blue dots at the top of the celery stalk.
