Transport/Photosynthesis/RespirationStations ResultsReview
Photosynthesis Funnel Lab
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
Tap Water Sugar Water
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 Animal Interrelationships
Bromo Plant Plant and Snail Snail
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!!!
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.
