  1. Turgor Pressure

  2. Demo In your journal- Write down what you observe about the piece of celery on the table.

  3. Turgor Pressure • Turgor is a forceexerted outward on a plant cell wall by the water contained in the cell vacuole.

  4. How does Turgor Pressure Work? Osmosis Osmosis • Water enters through the cell membrane. Moving from an area of high concentration to low concentration.

  5. Turgor in Plant cells • So, plant cells have a thick cell wall surrounding the cell membrane. • Plant cells usually have a big water-filled vacuole, called a central vacuole, that pushes out on the cell membrane to keep the cell rigid and tough.

  6. Turgor in Plant cells • If the vacuole loses too much water, it will cause the cell to become limp. • If too many cells suffer this fate, the entire plant will “wilt” and its leaves will lose their shape and strength and droop.

  7. If someone watered the wilted plant, what would probably happen?

  8. Plants cells have larger vacuoles because they have to store all of the food they make. Turgor Pressure: This plant is more wilted! This plant is more rigid!
