Biology: Photosynthesis Worksheet 1. What is the overall reaction for pho- To create glucose tosynthesis? 2. How does the overall reaction Since cellular respiration starts off to photosynthesis compare to the with glucose and ends with ATP, they overall reaction for cellular respira- are opposites tion? 3. Where does the energy for photosynthesis come from? The sun 4. What plant pigments are involved in -chlorophyll a photosynthesis? -carotenoids -xanthophylls -chlorophyll b 5. Explain why chlorophyll appears Chlorophyll is not good at absorbing green to us in terms of what hapgreen wavelengths so instead it repens to different wavelengths of flects them light that strike a chlorophyll molecule. 6. How does the amount of energy in light change as the wavelength increases. As the wavelength increases, the amount of energy decreases 7. Which colors of light are most efThe colors are in the blue to violet fective for photosynthesis? Explain range and the red to orange range why? because they can provide maximum energy for photosynthesis 8. In what organell of a plant cell does In the chloroplast photosynthesis take place. 9. What are the two stages of photosynthesis? 10. 1/2 -light-dependent reactions (light reactions) -light-independent reactions (dark reactions) (the Calvin cycle) In what part of the chloroplast does Light reactions take place in the thyeach stage occur? lakoids The Calvin cycle take place in the stroma 11. What happens to water molecules in They are split to give electrons, H+ the light reactions? ions, and oxygen gas (O2) 12. What photosynthesis waste product Oxygen gas (O2) is formed in the light reactions? 13. What two products of the light reactions are used up in the Calvin cycle? ATP and NADPH 14. What happens to carbon dioxide They are combined with each othmolecules in the Calvin cycle reac- er and the electrons and H's from tions? NADPH to form glucose 15. How can cells store the sugar that is It's stored as starch produced in photosynthesis? 2/2
