Transport photosyntheis respiration lab stations results

  1. 1. Transport/Photo synthesis/ Respiration Stations Results Review
  2. 2. Photosynthesis Funnel Lab
  3. 3. Photosynthesis Funnel Lab  1. Size of gas bubble can be measured to determine rate of photosynthesis.  2. Factors that can limit amount of photosynthesis are: Light, Water, Carbon Dioxide.  3. No sunlight, no photosynthesis, no Oxygen gas bubble.  4. Oxygen gas collected in test tube.  5. Increase light will increase photosynthesis.
  4. 4. Cell Respiration Lab Tap Water Sugar Water
  5. 5. Cell Respiration Lab  1. Sugar provides food (glucose) for the yeast.  2. Glycolysis in the cytoplasm, then aerobic respiration in the mitochondria.  3. Alcohol Fermentation  4. Balloon filled with Carbon Dioxide. Measure volume of balloon (Quantitative) Smell of Alcohol (Qualitative)  5. To compare the experimental group to determine results.
  6. 6. Plant and Animal Interrelationships Bromo Plant Plant and Snail Snail
  7. 7. Plant and Animal Interrelationship  All blue to start (bromothymol blue)  Control is BB only  Snail only turned clear/greenish  Color change due to carbon dioxide released by snail (respiration) making carbonic acid indicated by BB.  Plant photosynthesis, snail respiration  No light, no photosynthesis, carbon dioxide build up = color change.  Each takes in what the other releases!!!
  8. 8. Osmosis in Elodea Leaves  Hypotonic Hypertonic  Distilled Water Salt Water
  9. 9. Osmosis in Elodea Leaves  Structure of leaf cell is boxy and green.  Structure fits function because cells perform photosynthesis (green chlorophyll) and need lots of water (cell wall keeps cell from bursting – cytolysis)  Cells in salt water lost water, cell membrane shrinks away from cell wall.  Salt water is hypertonic, water moved out.  Hypotonic best for plant cells – water moves in.
  10. 10. Passive Transport Review  1. Osmosis is the diffusion of water.  2. Molecules move from High Con. To low concentration – into the cell!  3. Fresh water is Hypotonic.  4. Blood cells bursts (cytolysis) Hypotonic  5. Molecules continue to move in and out at the same pace at equilibrium.  6. Water moves out of cells due to osmosis reducing turgor pressure resulting in plasmolysis.
  11. 11. Passive Transport Review  Appearance of Blood Cells
  12. 12. Critical Thinking  A. Solution in Hyptertonic, Solutes move into cell , Water moves out of cell  B. Solution is Hyptonic, solutes move out of cell, water moves into cell.  C. Solution is Isotonic, solutes and water move in and out equally
  13. 13. Critical Thinking  1. A. 0.9% is isotonic, 0.7% is hypotonic, cell will swell and burst (cytolysis)  B. 10% is Hypertonic, cell will shrink.  2. Cell wall keeps plant cells from bursting.  3. Cells suffer plasmolysis (water leaves)  4. Solutes are equal inside and outside cell  5. Molecules continue to move at equal pace in and out of cells.  6. Pressure water exerts against the cell wall.
