Science Buddies: Plants Are on the Move! A Study of Gravitropism
As we humans zip from place to place, we often forget to stop and smell the roses. Compared to our fast-paced lifestyle, plants seem rooted to the spot. Don't be deceived by appearances however, plants are on the move. This experiment...

Science Buddies: How Do Roots Grow When the Direction of Gravity Changes?
You might not know it, but plants are able to sense their environment and actually respond appropriately. One of the key parameters that every plant must respond to is the direction of gravity: stems go up (opposite to the pull of...

Wikipedia: Gravitropism (Geotropism)
Gravitropism (or geotropism) is how a plant responds to gravity. Roots have a positive reaction to gravity and they grow toward it. Stems have a negative reaction and grow away from gravity. Learn more about what happens inside a plant...
