NettetThe _____ has two main ideas: 1. Amyloplasts—dense, starch-storing organelles—respond to gravity by being pulled to the bottom of root cap cells. 2. The weight of the amyloplasts activates sensory proteins, located in the plasma membrane, which initiate the gravitropic response. statolith hypothesis. flash furniture patio setNettetPlants respond directly to Earth’s gravitational attraction, and also to light. Stems grow upward, or away from the center of Earth, and towards light. Roots grow downward, or towards the center of Earth, and away from light.
