Staining Science: Capillary Action of Dyed Water in Plants
Have you ever heard someone say, "That plant is
thirsty," or "Give that plant a drink of water."? We know that
all plants need water to survive, even bouquets of cut flowers and plants
living in deserts. But have you ever thought about how water moves within the
plant? In this activity, you'll put carnations in dyed water to figure out
where the water goes. Where do you think the dyed water will travel, and what
will this tell you about how the water moves in the cut flowers?
