Presentation Transcript

  1. Chapter Eight – Cellular Transport and the Cell Cycle Section 8.1 – Cellular Transport

  2. Osmosis – The diffusion of water across a selectively permeable membrane.

  3. Diffusion - The movement of particles from an area of higher concentration to an area of lower concentration.

  4. What Controls Osmosis? • The unequal distribution of particles (concentration gradient).

  5. Cells in an Isotonic Solution: • In isotonic solutions the concentration of dissolved substances and water in the solution is the some concentration of dissolved substances and water inside the cell.

  6. Cells in a Hypotonic Solution: • In a hypotonic solution the concentration of dissolved substances is lower in the solution than the concentration inside the cell. Also, there is more water outside the cell than inside. The cell swells!

  7. Cells in a Hypertonic Solution: • In hypertonic solutions the concentration of dissolved substances outside the cell is higher than the concentration inside the cell. The cell shrivels!

  8. Passive Transport – Does not require energy to move particles across the membrane.

  9. Active Transport – Requires energy to move particles across the membrane.

  10. Passive and Active Transport:
