Photosynthesis

steps of photosynthesis.
Provide the equation for photosynthesis. Explain where each reactant comes from and how the plant gets it. Then, explain the
importance of each product for life on earth.
What is an absorption spectra? Explain why a green leaf looks green. Is it the same reason a red leaf looks red? Explain your
answer.
What is the main energy-carrying molecule in the process of photosynthesis? How does it carry energy? Where does it carry
energy?
Provide the reactants and products of the light reactions. Describe how the light reactions work. Use a diagram or picture.
Provide the reactants and products of the Calvin cycle. Describe the three phases of these reactions. Use a diagram or
picture.
Provide the equation for photosynthesis again. For each reactant, explain how it is used within the light reactions or Calvin
cycle. For each product, describe how it is generated by either the light reactions or by the Calvin cycle.

Part Two

Create a 7- to 10-slide Microsoft® PowerPoint® presentation addressing the following for each scenario, A-E.
Is the movement of a molecule an example of diffusion, osmosis, active transport, endocytosis or exocytosis? Why?
Explain the direction of molecular movement involved.
Use visuals for each scenario.
A) A semipermeable membrane bag containing a 30% sugar solution is placed in a beaker of pure water.
B) The cell membrane of a nerve cell keeps 14 times as much sodium outside as it does inside.
C) An Elodea (a freshwater plant often used fish tanks) leaf is placed in a 2% salt solution.
D) A cell engulfs debris from outside itself.

E) A cell makes protein that is headed for a different location within the plant.
