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.
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.
Plant and AnimalInterrelationshipsBromo Plant Plant and Snail Snail
Plant and AnimalInterrelationship 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!!!
Osmosis in Elodea Leaves Hypotonic Hypertonic Distilled Water Salt Water
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.
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.
Passive Transport Review Appearance of Blood Cells
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
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.
