Experiment 1
Water Flow: How do varying solutions of water affect the amount of water a plant takes in and its turgor pressure?
Purpose/Hypothesis
To maintain a stable environment, plants move water in and out of their cells until the concentration of water molecules is equal on both sides of the cell membrane. Osmosis causes the water to flow from a region of high concentration to a region of low concentration. As the plant cells takes in more water, the turgor pressure increases; when the plant cells take in less water, the turgor pressure decreases.
Changing the concentration of the particles, or solutes, dissolved in water will change the amount of water present. Adding salt to water, for example, makes the water have a high concentration of solutes, which is called a hypertonic solution. A low-solute...
