For photosynthesis lab in biology
1) This lab uses spinach leaves. Name another plant that would make an interesting comparison to spinach. Explain why you think this leaf would provide an interesting comparison
2) The lights used in this experiment are 60W. What would you predict the effect of having stronger or weaker wattage bulbs would be on your results? Explain.
3)This lab uses 0.2% sodium bicarbonate. What would you predict the effect of raising or lowering the percentage would be on your results? Explain.
4)What are TWO other things that might be manipulated in an experiment using this same protocol other than the type of leaf, percent sodium bicarbonate, and wattage of light bulb?

Why do you think that it led to an enzyme that also binds to O2 (which causes photorespiration that isn't beneficial to the plant)? 2) Explain what is meant by the statement: "C4 plants separate C3 and C4 processes in space and CAM plants separate C3 and C4 processes in time."arrow_forwardWHAT IF?

- Discuss Concepts Baobab trees (Adansonia spp.) store water in their trunks (stems) and, although the trees have leaves, considerable photosynthesis also occurs in the trunks. Cacti too have water-storing, photosynthetic stems. In terms of evolutionary adaptation, what does this information suggest about cacti and baobabs?arrow_forwardTest Your Understanding 12.

What does that suggest about the evolution of energy metabolism?arrow_forwardIntroduction The major context for this lab is photosynthesis, and the overall equation for photosynthesis is: 12 H2O + 6 CO2+ light energy → C6H12O6+ 6O2+ 6 H2O Exercise A: Photosynthetic Pigments Watch the following two videos about plant pigments and chromatography. To analyze the data we’ll give you, you’ll need to understand what types of pigments are found in a leaf, and understand some general characteristics of those pigments.

Also, we can’t deny the fact that as time goes by, the amount of carbon rises making it more complicated for the rest of organisms to adapt and survive. In relation to their specialized features, predict how C4 and CAM plants will each respond to a doubling of the concentration of CO2 in the atmosphere.arrow_forward1.
