Answers Below.
NOTE: not answers are below but most are there.
Chapter 8-1
1. Your diagram should be a copy of the lower right part of Figure 8.2
2. The reactants for photosynthesis are carbon dioxide and water (light and chlorophyll are also necessary). The products are a sugar - glucose - and oxygen gas.
3. The 2 main stages of photosynthesis are the light reactions and the Calvin Cycle. They are related because the products of the light reactions (ATP and NADPH) are necessary in order for the Calvin Cycle to take place (they supply the necessary energy).
Chapter 8-2
1. A leaf appears to be green because it contains a significant of the pigment chlorophyll. This material reflects green light (and absorbs light of other wavelengths).
3. ATP and NADPH
4. The light reactions take place in the thylakoids of the chloroplast.
Chapter 8-3
1. The inputs to the Calvin Cycle are ATP, NDPH and carbon dioxide. The output is sugar (glucose)
4. The direct product is a 3 carbon sugar G3P which is converted to glucose. This can then be stored as long glucose strings called starch, or it may be used directly by the plant for energy or for building material (as part of cellulose).
Chapter 8-4
1. From inorganic to organic - carbon dioxide is fixed to make sugar molecules in photosynthesis. From organic to inorganic - sugars are broken down into carbon dioxide (and water) during aerobic cellular respiration in order to release energy.
2. Carbon dioxide in the atmosphere helps trap heat from the sun that would otherwise escape into space.
