Turgor Pressure-Friday, November 19, 2010 7.7 C demonstrate and illustrate forces that affect motion in everyday life such as emergence of seedlings, turgor pressure, and geotropism Input Answer Below: _______________________________________ _______________________________________ _______________________________________ The ability for a plant and leaves to remain firm and upright is known as turgor pressure. Turgor pressure occurs when the plant cells of a plant exert force on the Output 1. Re-draw a plant cell labeling the 4 main parts. Color each a different color and make a key identifying what color goes to what structure. plant’s cell wall, causing the plant to stay upright. A filled vacuole that stores water will apply force to a plant’s cell wall, causing the plant to stay upright. The force of the vacuole must be greater than the force of the cell wall. When the force of the cell wall is greater than the force of the vacuole, wilting occurs. Wilting is the result of a plant not receiving enough water and nutrients, causing the plant to shrivel and eventually die.
